I take the pill but I haven't had my period

It may happen that, despite the use of the pill, menstruation is late in coming. A rare, but not impossible, situation that has several causes. We studied them together with the doctor in charge of the Department of Obstetrics and Gynecology Humanitas San Pio X.

Why does not the period come

Unless a low-dose oral contraceptive is voluntarily used, which can cancel the menstrual cycle without affecting the woman's health, such a situation can occur for several reasons. «The pill, in fact, works in 99% of cases. It therefore means that there is a one in 100 chance that it won't work, "explains the doctor.



Here are the causes possible:

  • The onset of pregnancy
  • An oversight
  • Too low dosage of the pill

1. The beginning of a pregnancy

As we said in 1% of cases you can get pregnant even if you take the pill. This can happen especially in the presence of:



  • taking other medications, for example antibiotics, which inhibited the correct absorption of the contraceptive in the gastrointestinal tract;
  • episodes of vomiting or diarrhea within 5 hours of taking the pill. If the woman has suffered from gastroenteritis within the month, or has had episodes of vomiting or diarrhea within a short time of taking the drug, her intake is impaired.

2. An oversight

"Another cause of pregnancy despite taking the pill is that the woman is convinced that she has taken all the tablets, but instead has missed one or more than one."

3. Too low dosage of the pill

«In some cases, menstruation does not occur because the dosage of the drug is too low and the woman is young. It is a situation that occurs especially in the case of polycystic ovaries. This is not to say that the pill is ineffective as a contraceptive. Simply, being too light, it is unable to make the endometrium grow and cause menstruation, which is nothing more than the exfoliation of the endometrial tissue and its consequent expulsion ».

What to do if your period doesn't come

In all situations, the advice when you run out of a pack and your period doesn't come is to take a pregnancy test. "Even if the result will be 99% negative, this excludes the possibility of pregnancy and avoids taking a new package of the drug which, in the event of gestation, could cause problems for the woman and the embryo".
