My last period was July 10-14. Three days later, my boyfriend and I had unprotected sex (July 17). Three to four days later, the same thing. I have been feeling kind of bloated, but I think it's too early to get symptoms just yet. I also feel crampy, but my period isn't due for another 2-3 weeks. Could I be pregnant?

He did not pull out both times,

Of course you could be pregnant, since you had intercourse. Pulling out, does not stop pregnancy, only lowers sperm that enters,

Signs now, happen in some women, so yes, it is possible.

There is no way to know or test now. You will have to wait and see if you have your period, and if you miss it, wait at least 10 to 14 days, late, and test with first urine of the morning

Apparenetly you are trying to have a baby right now, are you hoping for a boy or a girl, (maybe twins or triplets) You did everythig it takes. But as Fr_Chuck stated... its too soon to even test so the waiting game continues until it is.

But yes...there is a chance.

ANY time there is penile insertion there is the chance of pregnancy. You can reduce the chances, but not eliminate them. So yes you certainly could be pregnant. However it is way too soon for the symptoms you are feeling to be due to a pregnancy. The first physical manifestation of pregnancy is missing your period. If you do, then you wait another 2 weeks and you can start taking tests.
