Didn’t know I wanted a baby till now

Hey guys.. don’t really know who to tell. My bf knows and he’s sad but I don’t really know if it phases him since he really doesn’t care about having kids. He says/said if it happens it happens.

I had a miscarriage a couple of days ago at 5 weeks since last period. The day before the miscarriage I tested positive. I didn’t know how to feel then but now I’m sad. I didn’t know I wanted a baby. It’s hard not to blame myself.
