Question timeeeee

I’m 31 Weeks today, and have been having some odd things happen this week. First of all, my Braxton Hicks contractions have become a bit painful. Second, my ligament pain is back. I have a constant pain in my lower back. I know all of that sounds normal, but it’s just kind of throwing me off. Also, TMI part, I’ve been constipated this ENTIRE pregnancy, but the past week I’ve been able to poop like nothing is wrong. Sometimes it’s like loose stools, but not usually. I’ve heard in the past that your body starts to clean itself out before labor, and that’s a sign. Ive also had more discharge than normal. Always white or clear. I’ve had some pressure down there as well. Am I just being paranoid? I’m so ready for these babies to come, but not ready enough for them to spend weeks in NICU.

TIA
