As mentioned above, menstruation marks the end of one cycle. The end of your cycle is marked by your period starting, but there are no obvious signs that your body has begun a cycle. You can ovulate and not know it. You will only know you ovulated if you get your period or, if you had sexual intercourse within your fertile window , you get pregnant.
The medical term for a lack of menstrual cycles is amenorrhea. It can have many causes. If you have had regular periods, and then suddenly stop getting your period, you may be pregnant. This is likely the first thing you thought of when your period was late, and you have likely already taken a pregnancy test. But what if your pregnancy test was negative?
Could you still be pregnant? Exclusively breastfeeding a baby can prevent your periods from coming. How long will you go without a period when breastfeeding? It depends on how often you are breastfeeding and your personal biology. Some forms of birth control can stop your periods.
Your doctor should have told you if this was possible when they prescribed it. If you want to try to conceive, how long will it take for your periods to return after you stop taking the birth control depends on your body and your contraception choice. Other medications that may stop your cycles include some psychiatric drugs, chemotherapy, allergy medications, and blood pressure pills.
Obesity is one of the most common causes of infertility. Women who are obese may experience irregular menstrual cycles and, in some cases, their periods may stop completely. Losing weight may restart or regulate your cycles. With obesity, too much fat throws off the normal hormonal balance in the body.
If you are underweight, the lack of fat can throw your reproductive cycle off. If this is the problem, bringing your weight up should restart your cycles.

A girl with irregular periods usually still ovulates, just not on a regular, predictable schedule.
All girls, especially girls with irregular periods, can ovulate at different points from cycle to cycle. That makes it impossible for a girl to know when she is most fertile.
Irregular periods also can make it hard for a girl to know if she is pregnant, since she doesn't know when to expect her period. Ovulation predictor kits are fairly accurate at detecting a surge in luteinizing hormone, which triggers ovulation.

Aim to have intercourse at least every two to three days. Your doctor may prescribe clomiphene citrate Clomid to induce ovulation.
Clomid has been found to be an effective drug for stimulating ovulation. It has also shown positive results when used in women with PCOS. Weight loss or weight gain may also help. According to the PCOS Awareness Association , losing just 5 to 10 percent of your body weight can help regulate ovulation in women who are overweight. They may be able to provide you with meal plans and exercise guidelines, or point you to resources. If your irregular periods are caused by an underactive or overactive thyroid, your doctor will prescribe drugs that increase the thyroid hormone or block it.
