Cramping and bleeding. 😔

Mama

Last week I had my first u/s. I should have been around 7 weeks. They found a sac but no baby. Today (3 days later) I started having some period like cramps and now I'm bleeding light pink. 🙁 Thoughts? I'm just going to go through the night and see how it's going tomorrow and call my OB. More than likely I'm having another miscarriage. My last one was a missed miscarriage at 13 weeks so I never bled.
