Missed Periods – A sign of fertility as well as infertility

For many women of childbearing age, pregnancy is first suspected when their menstrual cycle goes haywire.

Missing your monthly period by a few days is not a significant concern. We are talking about missed periods by the weeks or months.

When this strikes you, the first question to ask yourself is “how old am I?”

The underlying reasons of a missed period vary by the age.

If you have just stepped into puberty, your periods may not have a fixed schedule as your body takes time to adjust itself to its new condition, usually taking 6 months to a year to do so. Unless you have had sex the month before, this should be normal. See a doctor should it take more than a year to adjust or if your last period was more than 6 months ago.

Speaking about missed periods in a woman in her late 40’s, menopause comes first on the list. Missed periods is not a menopause unless your last period was 12 months ago. Like the irregularity you have faced in your early years of puberty, your body has the same reason when it comes to menopause; that is, trying to adjust the body to stop menstruating.

Delayed periods are normal at the start and at the end of your fertile life

Missed periods occurring at other than the above mentioned ages (i.e. somewhere between 18 and 45 years old) can be worrisome. Whether it’s normal or not is a big question. If you are breastfeeding, pregnant or are on contraceptive pills, then yes, it’s normal.

Delayed menstruation can also be caused by reasons as simple as stress, overweight, underweight or anorexia, all of which may sometimes be overlooked. Excessive exercise, such as those done by athletes, may also delay menses.

If you think none of the above applies to you, then let us move on to more serious, but not uncommon problems which may call for a doctor’s attention. The most common problem women face is cysts growing in their ovaries, medically termed ‘polycystic ovarian syndrome’ or abbreviated as PCOS. Cysts are small fluid-filled sacs that develop in a woman’s ovaries. The word ‘poly’ refers to more than one cyst in growing in the ovary. Nevertheless, the presence of even one cyst may disturb your menstruation, let alone if it is multiple. Cyst tends to get bigger when the ovary fails to ovulate and release the egg into the Fallopian tube.  This is caused by, and in turn may lead to hormonal imbalances.

Delayed menstruation can also be caused by reasons as simple as stress, overweight, underweight or anorexia, all of which may sometimes be overlooked.

If you have had any abortions, cleaning of your womb (D&C) after a miscarriage, hysteroscopy or any other instrumental procedures done on your cervix or womb, adhesions are more likely suspected. Adhesions are fibrous bands forming between tissues and organs due to scarring. These block the flow of blood during menses and may trick you into thinking that you have missed a cycle. This, as well as PCOS, may cause infertility. If you are trying to conceive, it is wise to consider these possibilities.

Other less common causes of missed menstruation are diabetes, thyroid hormones imbalance, intestinal problems, tuberculosis and liver diseases. Don’t forget that side effects of various medications or drug abuse can also be a cause.

So, should you see a doctor right away? Don’t rush, don’t stress yourself up. Relax. Take a deep breath. Try to think of the possibilities of being pregnant. You might want to get yourself a urine pregnancy test to make sure pregnancy is not the cause of your missed periods.

If you’re overweight/underweight, reducing your weight/gaining weight helps restore normal cycles and fertility. Check your body mass index to be sure. Still not helping? Still not sure what is the cause of your missed periods? Looks like it’s time for you to see a doctor for further tests.

    • Dr Elaine Loh

      Hi Sara
      The fact that your period has stopped for 2 years, is not normal and warrants further tests/ investigations to identify the cause, especially with the weight gain. I would advise you to come in to visit one of our doctors for a consultation so that we can help you. We have female doctors if you prefer.

  5. My period is irregular, most of the time it’ll come later than the expected date. However my last period ended on 28th Nov 17 and I had protected sex with my bf on various occasion after my period ended. I also had stomach flu on 8th Jan – 12th Jan 18 and because of the viral flu, my food intake were all messed up and I lost a kg. I’m currently experiencing abdominal cramps, and when I go to toilet my poops are runny and also my boobs hurts for a week already. I also feel very bloated after every meal. I took a pregnancy test on 23rd Jan and it showed negative. Am wondering why my period isn’t here for about 32 days (based on the app)? So far there isn’t any spotting. Am I pregnant?

    • Dr Elaine Loh

      Some of the symptoms you describe are symptoms of pregnancy. However, they could also be pre-menstrual symptoms.

      If you are concerned, repeat another pregnancy test in 1-2 weeks time, or see a doctor for an assessment.

  8. Hi! I’m 24 & diagnosed with PCOS on both ovaries. My OB recommended me to take duphaston (2x a day) for 4days since I’m almost 2months delayed (my LMP was July12). She said I’ll got my period during or after medication, & I’m already on the 3rd day. I’m just curious of what would be the next step if ever my period will not arrive? Should I increase my duphaston intake?

    Before my medication, we had an unprotected sex with my boyfriend as well as on my first medication. Can I get pregnant? What would be the percentage?

    • Dr Elaine Loh

      The best person to direct these questions to would be your OB doctor, since she already has a treatment plan for you.
      Pregnancy is possible in patients with PCOS. There is no way any doctor would be able to tell you the percentage of getting pregnant.

This is the first time I’ve missed my period. I have taken several pregnancy kit tests but all turned out negative when period was late for 2 weeks. When should I be concerned and make a trip to the doctor?

      You could repeat a urine pregnancy test in 2 weeks time.

  15. I am 44 years old. Never missed my period since 13 years old. My cycle has always been a 28 days cycle. If ever delayed only for a week or two. But this time its for 2 months. I have never missed my period that long. Pregnancy test revealed negative. I had my period now… Did i have a miscarriage. Or just a missed period. I experienced the early signs of pregnancy, food cravings, eating a lot, tender nipples, full breast and bigger than usual tummy. Will appreciate your reply. Thanks

  16. Nicole

    I started skipping periods. Then didn’t have one for two months. I went to the doctor, and she told me, “It’s because you’re on birth control. I’m sure of it.” Well, I’ve been on the pill for 15 years and never skipped or missed. Now, I’ve missed four in a row.

    I am not pregnant (I’ve taken a test every month I’ve missed). I also told her I was having discomfort in my lower right abdomen and was spotting during sex. Again, something I haven’t experienced in 15 years of being sexually active. She told me it was probably my uterus, again because of the pill.

    She agreed to give me an ultrasound, and she said it came back clean, though I have no copy.

    My weight hasn’t changed. My health hasn’t changed. My stress levels are lower.

    If I’m not pregnant, and I don’t have any ovarian or uterine issues that are visible on an ultrasound, what could be causing this?

  17. I am a lady aged 25 my my cycle is 7 or 8 of every month. i had sex on the 16th of January 2016 now today is 11 February. I have missed my cycle.After two weeks of my intercourse, i had a terrible womb pain but now the pains had gone. I am worried i might be pregnant.

    • Hi Nlm,
      Thanks for the enquiry.
      I suggest you come to clinic for an evaluation of your hormone levels – an imbalance may be causing your irregular mensus.

  19. Hi, I’m 36 years old and married. We’ve been trying to have a baby for more than 8 months already. Now, I am 11 days delayed but been having spotting since the 5th day of my delay. I took a test on the 6th day but it came back negative. I am too confused. What could be the possible reason for this? I am also having lower back pains and a bloated feeling in my tummy.

    • It is still possible that you are pregnant. It is a little too early to show up as positive. You can re-test again after 1-2 weeks.
      If you are concerned, please see a doctor.

  20. Hello my name is Alexa. I have had irregular periods sense I first started.

    • There are many possible reasons for irregular periods. My best advice is for you to see your doctor to find out what is wrong before embarking on any home solutions.

  22. Hello,
    My period is regular I have experienced it coming a day or two early as well. I also experienced it coming late. I had intercourse on June 20 I was not ovulating and my period came a week later on time. Now we are in July and my period is supposed to be here and it is three days late. I am feeling nauseous as well. What should I do?

    • You are afraid you are pregnant? Wait a while more. If you period still does not come, do a home pregnancy test.
