I'm so sorry for your loss, Mikki. It's so heartbreaking when this happens. I didn't get to see a heartbeat before my first loss but I did with my second and allowed myself to get excited. Ended up having a D&C at 12 weeks instead. Be kind to yourself and allow yourself the time and space grieve. If you can, take comfort in the support of BB like I did and find hope in the success stories that are shared by those who have m/c but gone on to have their bubs.
Sending you lots of healing vibes and love.
