Miscarriage, Weaning, TTC

Hi 🤍

I have a 20 month old son. I’m a SAHM and bf on demand. Basically I don’t offer and don’t refuse. My little man is a great eater and gets tons of solids and hydration from other sources. My regular periods returned soon after having him despite EBF. I conceived my second when my son was 16 months, but lost her at around 13/14 weeks in a missed miscarriage. All labs and testing have come back normal. My regular OB doesn’t think BF played a role, but my high risk OB told me yesterday that she thinks bf could’ve contributed to the loss and she wants me to wean. I’ve already started TTC. Her recommendation really threw me. I do NOT want to wean, especially since my son is gaining covid immunity through my breast milk. I always wanted to let him self wean. I don’t know what the fuck to do. I might already be pregnant again. I really, really want another baby, but I really, really don’t want to wean and lose the physical connection/immunity that bf offers. Help!! What do I do??
