Threatened miscarriage

AWL
I am a little over 8 weeks and started having cramps Thursday night. On my doctor's guidance, I went to the ER Friday morning. We were able to see the baby for the first time, and she/he has a heartbeat of 179. Since I'm having abdominal pain, I was diagnosed with threatened miscarriage and need to have my beta rechecked in two days. This is my third pregnancy since January, one I miscarried and one was a chemical pregnancy. I'm really nervous, and hope that everything will be ok. Please keep us in your thoughts and prayers!
