I'm so scared because I have been on the mini pill.

I have been on the mini pill for almost 9 weeks(I had a miscarriage 9 weeks ago-I was 7 weeks and 2 days pregnant.)

I am having some pinkish spotting(everytime I wipe)all day, and slight pelvic discomfort. I am so scared I have harmed the baby by taking birth control. The only reason i took a test was because my taste was off and I've taken naps today(I'm always energetic so this is unusual for me).

Has anyone ever been on the mini pill and have had a successful pregnancy?

Please help I'm so nervous.
