Baby pressure...

Let me start by saying I never knew I could get pregnant. My left ovary has so much endometriosis tissue surrounding it it’s medically considered “dead” very minimal blood flow in 10% of it and the other 90% has no flow. My right ovary has about 50/50% so when we got pregnant with my son it was a miracle. I never wanted children(or had convinced myself of that because I didn’t think I could.) and my pregnancy was horrific he was slow growing, I started going into labor at 16 weeks and had to take multiple medications to stop labor my entire pregnancy. I bled constantly and was dilated two centimeters almost the whole pregnancy. He came a month early and it was just traumatizing. I never want another child. My husband supports that and we are ok with that. However my whole family all of our coworkers and friends are all telling me how awful it will be for my son to be an only child and we need to have one more. The pressure is so much. I tell them no I tell them I love children so much but my body isn’t meant for it and it was more than a miracle that I carried our son as long as I did and I may not get that lucky again. What if I get pregnant again and I lose it? Or I go into labor way early or something is wrong because my uterus doesn’t get proper blood flow? There’s way too many possible negatives to risk it. My husband thinks I hate him. I’m terrified to have sex. Not because I don’t want to get pregnant but because it freaking hurts. It feels like knives are in my abdomen during and after for hours. Doctors don’t want to remove my uterus because “your husband may want more children” I’m “only” 23 and they just don’t care what I want. I’m so tired of society telling me my purpose is to breed and raise children. My son is my world but that’s enough for me I don’t need three or four or even two. I just want to not live in constant pain! Women deserve to be heard. Women deserve to know their opinions on their bodies matter!
