Support?

I'm struggling a little bit. I've always been extremely sexually active with my current boyfriend. We just had twins via c-section in January. Well we've been using the pull out method because the OB absolutely refuses to work around my work schedule and doesnt cary depo at the office you have to go get it from your pharmacist and make a nurses appointment, that apparently they only have in the morning. I work mornings. But they were oh so happy to tell me if I get pregnant so soon after having my twins that I'll put mine and the unborn babies life at risk. A little background, I was put on pelvic rear at 16 weeks pregnant in October and we just recently were cleared for activity. We had a little mishap this morning where he didnt get out all the way before he started 😑 my anxiety is sky high. I wouldnt mind if I was pregnant, but I'm terrified that something would happen to me or the baby. YES I know condoms are a thing. Every one I use causes itchiness. I've tried latex free, sheepskin idk what else to try on that front. I do have a latex allergy so that's out of the question. They also made sure to remind me a dozen times I'm at a higher risk of conceiving twins due to just delivering twins. What should I do on the being refuse birth control aspect? Please if you are going to be disrespectful dont even bother just move on ok?
