I had my period April 23-27. My bf & I had sex April 30 without a condom for literally 5 seconds just to see how it felt. He pulled out & nothing got inside. Then he put on a condom after that. I took the plan B pill About an hour after just to be safe. A week later, May 6 I start bleeding & it’s as heavy as a normal period. I only bled for two days May 6 & 7. I did some research & saw that bleeding can be a side effect of plan B. I’ve taken the pill one other time probably a year ago & I had no side effects. Is this something I should be worried about or is it just a side effect?
