When do you tell your parents?

Kat

I’m due July 8th or so won’t know for sure til first appointment next Monday. 5 weeks 1 day today. I really want to tell my mom I’ve known for 2 weeks but we wanted to hold off until after first scan but it’s killing me. I don’t really feel pregnant but BFP with every test I just want to tell her but don’t want to break her heart if we lose another baby.
