Does Plan B Make You Bleed?

To put it simply, yes, using this medication may cause you to have irregular vaginal bleeding. The reason for this is plan B essentially overloads one’s body with hormones, particularly progesterone, which tricks the body into believing it is pregnant (progesterone is naturally occurring in pregnant women). This halts the progress of ovulation for a short period of time, soon after you will experience a rapid decrease in the hormone, which can cause bleeding. This is due to the production of a thick uterus lining which has built up in preparation for pregnancy, as the levels of progesterone drop, this building up in the uterus lining is passed. Essentially, plan B causes bleeding as it leads to a hormonal balance, albeit temporary, within the body.
