I'm a little worried

Nicole
So I'm about 7 1/2 weeks pregnant. Have my first appointment this Friday. But last night the hubs and I had sex, usually he's on top but last night I was on top. And about 3-4 hours later I have some pain in my abdominal region. And it's still continuing this morning. Anyone else have this problem? I just don't want anything to happen to the baby.
