I had my iud removed about 3 weeks ago. Had it for over 3 years, started on the pill the day it was removed. I had unprotected sex with my bf the first week. What are my chances of being pregnant? I've been having some early symptoms of pregnancy, so I'm a little nervous I might be. Also I didn't started my period until 3 days after mirena was removed and it only lasted for 3 days, it was somewhat light bleeding.
