I don’t want to put anything in my body

Monday I will be 2 weeks pp. My 6 week check up is the day after my husband and I’s anniversaries. 9 years together and 1 year married. Well before I got pregnant with my first son I was taking birth control pills. I couldn’t remember to take them every day at the same time. Before I got pregnant with my second son I was using Mirena IUD for 4 years. It was great till I started having irregular periods and becoming super bitchy. My hormones were all over the place! Throughout my pregnancy I was telling my husband I don’t want to use or place anything in my body anymore. I’ve been asking him would he mind using condoms. I honestly don’t want to get pregnant anytime soon. My husband just laughs and flat out tells me no or he’ll say I’m not wrapping shit up it’s my pussy. He can’t wait for my 6 week check up and even if I’m cleared I don’t think I’m ready for sex. And I told him this and he told me I’ll be fine and ready for sex. I’ve also told my husband I’m more fertile and I can get pregnant quicker and easier. You’d think he’d be like okay with condoms, but he’s more like we will be fine. He’s okay if I get pregnant he even says his mom was pregnant at her 6 week check up. My husband and sister in law are Irish twins. I’m not ready for all that. I don’t think I’d be ready for 3 kids and I’m still traumatized about having my second son. My labor was easy and delivery too but my son had to go to the NICU the first day was rough for him, he wouldn’t eat, his blood sugars were supper low and that scared the shit out of me. I was so stressed out and scared. Why would he wanna go through that again?
