5 wks and pain.

Savannah • I have a 4 year old daughter and am currently pregnant with a baby boy!!
I'm 5 weeks today and I have a pain in my uterus. Sometimes it's just a slight uncomfortable twinge and sometimes it's a sharp, scary pain. I never had this with my first child. I had the Mirena and was always scared something might have been damaged inside. Anyone else experiencing this? My first OB appt is Feb 3rd.
