I was 4 weeks when I found out and I had cramping all through the 4th, 5th, and a little in the 6th week. I was all worried but it's normal as long as there's no bleeding! And even then you're not supposed to panic because some women bleed.

I believe its ligament pain part of the growing process

Thank you, I have been cramping ever since I found out and now I have having this pulling feeling! I didn't know if I should go to the doctor since I don't go in for another two weeks!

Yes your uterus is stretching! i found out I was pregnant because of the cramping! It went on for a while for me but not everyone. Congrats!
