Labor signs ??...

Paige

Alright so this is strange I know I have two kids already, but my water broke before I had any labor signs and I of course was already in the hospital and didn't experience much cause I had c sections. I'm almost 36 weeks with my third this whole pregnancy has been rough on my body I was intubated and life flighted at 13 weeks and have practically been put on bed rest by my husband haha, today I woke up and my boobs were rock hard! This happened after delivery with my first two, I feel like my stomach has gotten smaller, I'm having a ton of discharge and its watery not bloody or creamy just watery, went grocery shopping and had intense lightning crotch/ cramping the whole time, my back and hips hurt so bad I could cry, my feet are swollen, baby has most definitely dropped, and all day I've been eating but I feel like my stomach is empty, baby is moving around but he has calmed down in there compared to his usual activities. My question is are these early signs of labor? Should I call my doctor
