Hello everyone. It's my third pregnancy and it's been really tough. I have so many aches and pains. The thing is that I have frequent contractions, my belly constantly feels like a balloon, now I'm at 38 weeks pregnant, and my belly again feels like it's going into labor, like a real contraction... In previous pregnancies, I had contractions that were different, they would pull down on my lower abdomen and my waist would hurt. On top of that, I got sick with a cold, my nose is stuffy, my head hurts, in general, I feel awful! I want to cry! I have so many questions: do these contractions happen? What causes the belly to feel like a balloon?
