It's twins, now help!!!

An
So I am 6 weeks and 4 days!! At 5 weeks and 6 days I went to the ER with sharp pains, no bleeding and an ultrasound confirmed my husband and I are having twins!!! We're so excited after our MC of our daughter at 21 weeks in August. Looks like di/di twins doctor says. Today I was laying in bed and had shooting sharp pains on my left side from my stomach to my back :-(. Been a little nauseous but no vomiting and super crampy. Anyone else experience this?!! Thanks❤
