My sister says what I am getting are contractions, but i'm just not sure.

sometimes I get low "pain" in my back, and then it starts feeling like I am about to get my period. Some times my stomach gets hard, and the baby rolls around, and i'm not sure if its her streatching, or a contraction? I don't know. I also just get nautious every so often, then it goes away. But I am getting a lot of brown discharge, which is really grose! Lol!
I'm going to miss being pregnant. But I think at first I will be too happy to get her out of me! Tired of not being able to move around so easy. Hehe!
I'm sooo excited!!
