I want to share my experience with plan b, actually I took My Way what is the exact same thing just less price! I had an incidence during sex. The condom broke but he didnt come tho. But still i was worried about pre-cum and at this time i was right before ovulation, so I took the pill on the next day around 17 hours later. The following week my stomach hurt and I had cramps in my abdomn sometimes. After one week I started bleeding for 5 days what was 1 1/2 week earlier than my actaul period is supposed to come and it wasnt like a normal period, because it was really dark almost black and it seems so it would only come when i needed to go to the bathroom.. in the following week my abdomen hurt at different parts, I feel bloated and my breast got very tender and start hurting after 3 weeks and my back was hurting as hell. Than after 4 weeks i got weird bleeding again, which was very heavy but just last for 2 days. It didn't looked like a real period either. I never took a pregnency test during this time because I was to scared of the outcome. During the next 5-6 weeks I feld bloated, a bit nausy and almost every symptomse you could experience during pregnancy. But around 10 weeks after talen plan b (MyWay) I finally got a real period. It was scary time, but plan b can cause every symptoms like pregnancy! The best thing is to do is be calm and don't read to much about symptoms because the only thing that makes you smarter is doing a pregnancy test. Plan b can really mess up you cycle, like it happened to me. Iam sorry if I have some spelling or gramma mistakes, my native language is not english, but I really wanted to share my story!
