Cramping

I'm just a little worried. Two weeks ago I had a positive test, well 8 positive tests lol, I've had cramping through the entire month before the positive test, and since getting the news. Is it normal to feel pretty frequent cramping? It's not painful, just feels like mild period cramping, it gets a little stronger if I've eaten, am gassy, or feel the need to make a BM. I've had no bleeding, except for a few days ago after having sex, I think there may have been a little spotting, or I'm just being paranoid.

I'm estimated at 6 weeks right now, can frequent cramping be normal?
