Anyone have any ideas?

I am 7 weeks and 3 days. This is my 3rd pregnancy.

I get sharp pains here and there and also a lot of round ligament pain... which to me it seems way to early.

When I sit on the floor it in the couch I like to hug my knees but that uncomfortable now and I will get sharp pains around my uterus not ligament.

It just seems my uterus is super sore... it's been a long time since I've been pregnancy again and I don't remember this so soon. Especially don't remember round ligament pain til much later on.

I'm terrified of miscarriage since we've been through one. Any insight would be nice!
