Consistent cramps with lower back pain.

I can't help but be nervous. I've had light cramping on and off and some round ligament pain over the last week or 2. Today I started getting different cramps. They're not super painful but consistent. For the last 5 or so hours I've had constant cramping and some low back pain and I cant help but think this could be another miscarriage.

Just venting I guess as I know there's nothing I can do.
