Cramping at 8 weeks 3 days

Veronica

Ive been feeling menstrual like cramping all day today as well as some lower/buttock pain. I went to get an ultrasound at the ER two days ago and all tests were normal. The heartbeat was 152 bpm. I'm terrified I may be beginning to miscarry because of the cramping that's very similar to my period cramps.

Is anyone else experiencing this???? HELP!

I'm having bad anxiety over this and I can't go back to the ER again...
