I just finished my menstrual cycle 4 days ago. Two days ago, I had sexual intercourse and may have had an accident, where my partner s semen may have gotten inside of me. I am uncertain what happened, we thought the condom may have split; however, it didn t look like any semen was inside of the condom from what we could tell. It was very mess all over my vagina, possibly inside of me and all over his hand. As we were cleaning up we both were concerned and I am not sure what in the world happened. Is there a possibility I could be pregnant? Would Plan B be an option to take? I am very nervous, please provide guidance.
