I had my period last week & then had sex two days ago was rough yesterday i start bleeding lo ke i am on my period again is this normal !?

Hard to say: If you are a woman who does not have regular periods and has occasional episodes where you lead, then this might be normal. However if you have regular periods every single month, then you should see a gynecologist to check you for infections and a normal pap smear. You should also talk to your doctor about being on birth control if you are not ready to get pregnant.
