I had a medical abortion 2 1/2 weeks ago. I went in for my follow-up ultrasound and they told me the pills "cleaned me out" and that my endometrial lining is very thin. I went to get on birth control immediately following my ultrasound and started taking the Ortho Tri Cyclen that night. I took it two nights so far, at the same times, and now today I just started bleeding and cramping. Is this normal? I did have unprotected sex with my partner one day before my follow-up as I was not bleeding or feeling bad down there, but he used the "pull out" method. We have started using condoms again.
