While your period and ovulation are both parts of your monthly cycle, they are not necessarily linked directly with one another. That is to say that your period and ovulation are distinct parts of your cycle. This means, primarily, that the two won’t happen at the same time. This is about all that you can say with certainty about their relationship. This means that, if you are not having a period, you can still ovulate. Obviously, you can also have a period if you are not ovulating.
To understand how you can ovulate and still not have a period, you need to understand some basic things about how the woman’s monthly cycle operates in terms of the timing of the period and ovulation. Ovulation occurs prior to the start of the next period, right around 14 days prior to the start of the next period for the woman who has a 28-day cycle. This means that a woman may ovulate one month, and then not have a period the next due to any number of causes.
It is not uncommon at all for a woman to miss a period, or not have a period for a time. There are a variety of possible reasons that this might happen, as well. For example, low body weight can cause a woman to miss periods. In addition, strenuous exercise has also been shown to cause a woman to not have a period. However, during these times that the woman is not having a period, she may very well still be ovulating.
Not ovulating is a completely different situation than not having a period, and can be caused by completely different things. Not ovulating is known as anovulation, and it can be caused by things like illness, stress, thyroid problems, luteal phase defect, polycystic ovarian syndrome (PCOS), the use of contraceptives, and many other things. As women who use birth control pills, it is possible to have a period but not ovulate.
There is one other thing to keep in mind in this regard. A woman can still become pregnant during her period. If she has a short cycle, and her ovulation occurs near her period, the sperm could, in theory, live long enough to fertilize an egg, as sperm can live for between 3 and 5 days in a woman’s body.
