am 7 days late for my period. I had unprotected sex almost a month ago and he finished inside me. Well for the last week or so I have been feeling sick at night when I go to lay down and sleep. I am moody and tired all the time now. I have random cramps that go away when I use the restroom or pass gas. I have also been having allot of gas lately which isn't normal. My period is never late after my miscarriage two years ago. Could I be pregnant?

Yes, it is possible, since you had sex. Even if he did not "finish in you" there are sperm in the early fluids, so pregnancy can happen. Even with birth control, pregnancy happens.

So wait about one more week, and test with first urine of the morning

With being a week late, and having symptoms, try a pregnancy test or see your doctor for a test in office.

"and he finished inside me". No protection on his or your part? That's how babies are made!
