Preterm labor?

I’m 32 weeks and 3 days today. For the past 4 days or so, I’ve been severely uncomfortable and sore. I know that’s completely normal, but it’s been nonstop. Yesterday morning, I’m pretty sure I was having Braxton Hicks. I was hurting, my boobs started leaking, but the pain eased up. I was sore still and had my round ligament pain and just felt immobile, but I could deal with it. It felt like I just did 209 curl ups and my abdomen muscles were left sore. Early this morning, I woke up around 6 am with this pain in my lower abdomen. I thought it was going to be the same way as yesterday, but it’s been a nonstop pain. It feels like a bad period cramp that’s not going away and it’ll get more sharp and then go back down to the consistent pain. I’ve tried walking around, I can’t go back to sleep, and now I’m having diarrhea. I’ve been this way since waking up at 6a and it’s 10a. I don’t know if I was having constipation cramps or if it’s just bad Braxton Hicks or what, but I’m so uncomfortable and just want to find a way to help it stop. I’ve been pregnant before, but It was with twins and I had to deliver at 21 weeks. I don’t know what’s normal and what I’m supposed to be conferenced about. 😩 I haven’t had no bleeding or leaking. I just don’t want to call my doctor and sound silly if it’s just constipation or Braxton Hicks. I did take pain medicine this morning and that didn’t help.
