We’re all familiar with the not-so-fun side effects of menstruation, including the bleeding, cramping, and mood swings, to name a few. But there is one part of the menstrual cycle that typically only those trying to conceive are familiar with: the ovulation window. In its simplest form, the ovulation window represents the few days of the month where pregnancy is most likely. During your menstrual cycle, hormones make the eggs in your ovaries mature, and once ready, they signal your ovaries to release a mature egg. This is the time in which fertilization of an egg can occur.
“The egg is released from the ovary during ovulation and has to be swept into the fallopian tube, and from there it travels through the tube, unites with a sperm, and the fertilized egg rolls the rest of the way down the tube to the uterine cavity where it implants,” explains Wendy C. Goodall McDonald, MD, an OBGYN in Chicago, IL. “The ovulation window represents the time from that initial release of the egg to when the egg has passed the point of no return in the fallopian tube and is too late to fertilize, which is typically 3-5 days.”
As you can probably tell, your ovulation window is kind of a big deal, especially if you’re trying to get pregnant. But because the OW is such a mystery to many women, we asked leading gynecologists to explain some of the most important things we should know.
Everyone’s “ovulation window” is different
Generally speaking, if you have a regular 28-day cycle, your ovulation window is likely somewhere between days 12 and 16, explains Anate Brauer, MD, a reproductive endocrinologist at the Greenwich Fertility and IVF Centers and assistant professor of OBGYN at NYU School of Medicine. If you have a longer or shorter cycle, the timing of your luteinizing hormone (LH) surge changes, so she suggests using an ovulation predictor kit for a couple of months to get an idea of when you are surging. “If you find that the kits are not working for you, consult a fertility specialist who can monitor you with ultrasound and blood work and can tell you when you are ovulating,” she adds.
