Should i be worried that i'm bleeding heavily after having intercourse? i'm 14 wks. pregnant.

Likely no: It's hard to asses your bleeding over the internet. If you're bleeding like a period, then that would be a reasons to go to the emergency room. If you're bleeding is light, then could be due to bleeding from cervix, which is common in pregnancy. There's never any harm to going to er and getting checked out for bleeding in pregnancy, better safe than sorry.
