I am 4 weeks pregnant, just yesterday morning I was light light pink spotting as I would clean myself and just spots in my undies. The cramping is no more than a period cramping nothing extremely severe. I went to er anyways and they did an ultra sound just to see there's no abnormalities even tho they can't really see a " full baby" yet they said it was fine as well as the vaginal screening. I go back to er or my ob to see if my hormonal levels are doubling in two days. Now even this morning I'm cramping a little bt no heavy bright blood. Has anyone else experienced this and continued a healthy pregnancy? Or is this signs of miscarriage, I'm sooo worried and been praying my butt off.
