My ovulation day was April 29th and I had sex on that day it is know may 14th and I got my period on the 12th but it is extreamly heavy more then normal can anyone tell me what is going on I am a little worried.:confused:

Well first of all was he a new partner ? If he was as old people say when you have sex with a new person it changes things in the body, but if was someone that you are having sex with regularly it was normal for your cycle to change.

It is not uncommon to have irregular cycles now and then. If the bleeding is a LOT heavier then usual,(esp if more painful then usual) you might want to consult your doctor, just to see if all is all right. It could be completely normal for you, or it could be something you might need medical attention for.
