Progesterone Shots & Labor

I’ve had two of my babies at 35 weeks. Which my doctor considers preterm. I’ve had 9 miscarriages. but delivered my other two fine. One at 38 weeks and one at 39 weeks. With my last one I was put on vaginal suppositories. She came out at the 39 weeks. This is my fifth viable pregnancy. My dr. Started me On progesterone when I reached 16 weeks. I get one shot every Wednesday. (It hurts, I’m in pain. And contractions get worse).

My question is: for those of you who have had to go through this...after the shots were over (mine will end when I reach 36 weeks 😩 so 16 more shots to go!) When did you go into labor?
