So Me and my bf did it June 8 I'm not sure when the last time I had my period was but I usually get it end month beginning new month, i took the plan b june 9 exactly 18 hrs after. I took it and around 6-7 days later I started bleeding, it started off brown and light and the second day it got heavy with clots but it ended around the 3 day. It's July 12 and i still haven't gotten my period. I've taken 2 pregnancy test both negative but I'm so scared, it's been more then a month after the plan b and still no period. I'm not sure if the bleeding I got was my period but I did get a little heavy the second day. I'm just really worried please Help.
