Pregnant? Or something else?

[bam-boozled]

Last night, after my boyfriend and I had sex, we noticed there was blood (on both of us.) It was a decent amount, but not too extreme. Kind of like period blood, but a less, and a little lighter.
I noticed I stopped bleeding this morning, after I used the bathroom.

The thing is, I've already had my period this month, and it was about a week or so ago. I've also been having abdominal pain, feeling extremely tired, headaches, slight nausea here and there.

Could I be pregnant?
Or is it something else?

Also, my boyfriend and I have had unprotected sex many times.
I haven't gotten pregnant, though.
I'm afraid I'm unable to conceive because of how many times we've tried and nothing happened.

We had sex right before my period, and right after.
Now the whole bleeding after sex last night happened.
What does it mean?

It doesn't really sound like anything to w0rry about. I know that spotting can occur during the beginning of pregnancy, so maybe take a test if you really think you might be?¿
But what it sounds like to me is that he may just have torn the skin inside you a little. If you guys were being a little rougher than usual this could have happened ~ i get that every so often. It's nothing to worry about really. But if it starts happening a lot you might want to get it looked in to as it could be an infection or something.

i'm a bit confused by your post. are you trying to get pregnant? if not.. then unprotected sex isn't a great idea. if you've had unprotected sex on numerous occasions i wouldn't write off the possibility of being pregnant even though you've had your period. i've heard of people getting their period and still being pregnant.. can happen.

Could be implantation bleeding.
Wait about a week, then take a test.
