Its the day my period ended so my boyfriend and I wanted to have sex but we didn't have any protection. So he stuck it inside then pulled right back out because we were scared. I read that you can still get pregnant from pre-cum so the next day I took Plan B. I took it and didn't get any symptoms. But six days later there is spotting and it's brownish but there is more than a few drops. It looks like a period but I just got off mine 6 days ago. Does this mean plan B is working? I'm terrified I'm pregnant. I read spotting is also a symptom of pregnancy. Someone please help.
