Implantation bleeding?

I was on my period for three daysand then on thethird day my period stopped because me and my boyfriend had sex and he cumd in me then three days later had spotting a redish brown so if you could help me!a!!

Just go see a doctor. For all we know, you can have a kid on the way. No matter what others say you can get pregnat on your period. Ans see, this is why from a young age we are taught NOT to have sex when on or periods. Because it's unclean, and now look what happpened. Another possibility is that you got something into your bloodstrem! Because you bleed out doesn't mean things can't get in!

POINT: See a doctor and don't ever have sex on your period again! [unless it's like at the dead end of it, I hear it's OK to do it then...But still]

Exactly, you need to take a pregnancy test, the only reason why pregnancy is an option is because you stated you had sex, anytime you have sex, pregnancy can always be a variable, I would consider that you talk to your local doctor, and find out what is going on, anyways, good luck. :]

Allowing your boyfriend to c*m in u, when your seeing your period is really unclean, knowing the known fact that you cud be pregnant as the same time, see a doctor you cud be pregnant and you cud develop an infection
