Babies 🥰

So I’m be been with my bf for four years we.. we got pregnant on accident a year ago..and i miscarried at 3 months. Fast forward to now he talks about starting a family and I’m not there 😕 all I can remember is the pain of my miscarriage and I have uterine fibroids so my chance of carrying full term are not certain and it all scares me NOT ONLY that but I’m just not ready at all I don’t feel like I’m where I wanna be. I need advice on my approach on a serious conversation because when he talks about it now I just say nah with my funny facial expression lmao.
