I had sex about 2 weeks ago and the condom broke, as my playmate came. So we had to get the Plan B pill. The Plan B box does list such temporary side effects, but I'm wondering if there is lingering side effects than we really don't know about. Since taking Plan B, I have noticed that I easily get very upset and grumpy by little things that wouldn't normally bother me. I've had some emotional moments where I broke down crying. I am usually patient about things but have found myself being impatient. I am just wondering if Plan B has pushed my body chemistry out of whack. And by body chemistry I mean emotions too because our emotions are produced by such chemicals and hormones in our body. Is this just me or has anyone experienced similar?
