I had my normal period at the end of May and then I had sex with a condom but the condom came, inside of me. I took the Plan B pill the very next day and then exactly 7 days later I had a mild period. I bled for about 3 days and the 1st day was like a normal period and then they subsided. I then had sex 2 times the next 2 weeks later but my boyfriend didn't ejaculate inside of me. I clearly saw that he didn't..It is now 4 weeks later & I haven't seen my period, but I'm cramping and I'm not having any pregnancy symptoms. Should I take a test? What do you think? Please help????
