First time this has ever happen?

this might be tmi but it is the middle of the night and i'm concerned and i'm going to ask anyways. Tonight after sex i begin to have some bleeding. This is the first time this have ever happened to me. I finished my term 3 days ago so i know its not from that. And the sex wasn't anything crazy or wild but i be on top and went a moment or two more vigorously because i required him to finsh fast wreak i was tired. I do not enjoy any std's and no signs that i may have any type of infection. So have anyone experienced this before? Do you know what cause it? I am definately going to call the doctor but any insight would be great.

Is within something I can do or eat to engineer my period shorter?

I don't deem it's anything to worry almost. Its happened to my a couple times.
1) If I have just concluded my period and he go too deep it would sometimes create me to bleed.

2) If it's vigourous, rough, or just cavernous it can happen. Its basically him tearing or hitting something inside.

If the bleeding doesn't stop it COULD be a torn membrane...I have that problem after my FIRST time.
Anyways if you are worried talk to you doctor for sure
hope this help

It could be old blood from your extent. This happened to me once and it freaked me out. If you enjoy pain inside you, after it's probably not old blood and it wishes to be evaluated by your doc. I hope this helped you, moral luck =] x
