I am currently in the same boat. But, I took plan b about 10 years ago as well, and did not experience any bleeding at all. That time I turned out to be pregnant. So I don't think anyone is pregnant, in just wondering if anything wrong and if I should see an OB. I hope that helps!
I took the plan b 1 step pill oct.2017 maybe the second week of October. I had serious cramps after taking the pill but I didn’t have any blood. But the cramps were horrible could barely walk couldn’t even go to class after work. I think I got my next period late like nov. 1,2017 it was pretty short like 3 or 4 days it was also extremely light. Here I was thinking i got off Scott free one day I had random bleeding for about an hour then it went away ... very odd I had sex that night two. 5 days later same thing happened except for the sex two days later same thing at this point I was actually looking for a period but was very confused happy but very confused. Thanksgiving rolled around and it’s been a constant flow ever since .... light/medium period no cramps which I usually am a horrible cramps who gets back pain too. It’s been 10 days so far but it feel like it’s been a month lord help. I talked with the front desk girl of my doctors office over the phone she said I should come in December if it doesn’t stop. I feel that they will put me on birth control .... I know the birth control helps with balancing hormones.... I’ve began working out to see if that helps .... I like healing naturally
