Currently wondering if I'm having BH. I haven't had them my entire pregnancy (not that I've noticed.) I'm one of those people who had severe menstrual cramps when I wasn't pregnant (pre birth control) Like in the fetal position sobbing and no pain relievers worked for me. So I feel as though my tolerance is high. All night I've been experiencing moderate menstrual cramping and lower back pain, I've been tossing and turning and have barely slept. I've been feeling like I have to poop but when I go nothing comes out. I've had a feeling that my baby was going to come early this entire pregnancy, but not this early. I have feel like he will be here in a few weeks to a month vs 8 weeks and 5 days.... Idk. But I keep having this feeling that I should get everything done because he's coming, not paranoia or stress, just a strong feeling that I need to be ready to go.
