My boyfriend and I sex just as a got off my period (no blood) on March 11. He used a condom but it seemed to be slipping and he also pulled out. After having a bit of a breakdown in fear I was going to be pregnant he went and got plan b for me. I took plan b less then an hour after we had sex. Five days later on March 16th I got my period and it was only 4 days long. For just about a week I have been experiencing bloating, which is weird because I usually never bloat. I have been very stressed out with school and being pregnant lately and today on April 14th I have been having some cramping and saw spotting in my underwear while going to the bathroom. Is there any chance that I may be pregnant after using withdrawal method, a condom, and plan b?
