Plan B, delayed period

Hello problmatic,

Changes to the menstrual cycle are a reported side effect of Plan B.

PlanBsideeffevts explains this very well: " Plan B contains high levels of progesterone. Progesterone is a hormone that naturally occurs in a woman’s body when she is pregnant. Progesterone slows down the ovulation process or stops it entirely which is why it occurs in such high levels while a woman is pregnant. You certainly don’t want to be ovulating while you’re already carrying a baby. When you take Plan B, you are getting a high dosage of that hormone which in effect tricks your body into thinking it’s already pregnant which stops the ovulation process. When the hormone level begins to decrease rapidly (not long after you’ve taken your medication), your body then thinks you’re no longer pregnant and begins the ovulation process all over again. This is also why some women experience bleeding or spotting after they take Plan B. Your body passes the blood rich uterine lining and bleeding may occur at this point. "

"Because you’ve created that imbalance and the internal confusion, your period could easily be delayed after you take Plan B. Sometimes it’s just delayed by a few days. Other times, it may be delayed by a week or more. For some women, it takes two or three months for their menstrual cycle to get back on track. You would still get your period in that time, but it could be later or earlier than it normally would be. "
