Is pregnancy possible if my partner or I have an irregular menstrual cycle?

About one third of all females experience an irregular menstrual cycle at some point during her life. This can be frustrating if you are trying to conceive (become pregnant). Stress can have a huge effect on fertility, so it is important for you and your partner to try to remain calm and supportive of each other as you are trying to achieve conception.


To reduce stress you both can:

  • Communicate openly with one another.

  • Get emotional support from a counselor or group.

  • Exercise regularly and try stress-reduction techniques, including yoga and meditation. You can also check out our article on how to give a massage.

  • Discuss a medical treatment with one another.


The first step in determining a female’s fertility would be to buy an ovulation test (available at many grocery stores and drugstores). Ovulation occurs once per month around the 14th day of a female’s menstrual cycle (day 1 is the first day of bleeding) and marks the most fertile period of her entire cycle. A positive result on an ovulation test means that a female would most likely be fertile over the next two days. By having intercourse during this two-day period, the female would have the greatest chance of conceiving.

If a female has used an ovulation test for a while and has determined that she is not ovulating, or if you have had unprotected and regular sex for twelve months without conceiving, it would be wise to contact a reproductive endocrinologist (RE), otherwise known as a fertility doctor. Irregular periods without ovulation can be caused by Polycistic Ovary Syndrome (PCOS), endometriosis, or other conditions that require medical treatment.

If a doctor has ruled out these conditions, the female may be prescribed fertility medicine to stimulate ovulation. Typically these medications are orally ingested (taken by mouth) and will stimulate the ovaries to produce eggs.

It is also important to check into male fertility. About one-third of infertility cases can be attributed to male difficulties. To have fertility checked, a male will provide the doctor with a sample of semen for analysis. The doctor will check the sperm count and make sure there are no abnormalities present.

The good news is, after testing both the males and females for the cause of their infertility, about 85% of couples will become pregnant and most pregnancies will occur within the first year of treatment.
