First miscarriage

I just recently had my first miscarriage too. I went to the local hospital because I was cramping and bleeding quite heavily. There's nothing really they can do unless you want some pain relief so you could just go see your GP.
I'm also a negative blood but I didn't need an anti D injection because I was only about 5 weeks pregnant. I also called my obstetrician who delivered my first 2 babies and he confird I didn't need the anti d but sent me for a blood test to check my antibody levels.
It doesn't matter if it's your first or if you already have kids but a miscarriage still hurts for many reasons, mostly all emotionally. Rest up if you can, I felt tired and a bit off for a few weeks. And just know that it's not your fault and nothing could have stopped it. Sending hugs and good vibes your way.
