Am I OK???

I had my daughter nearly a year ago (03/29/2019) with vaginal delivery. I was induced because she was abornmally small, but besides that, totally normal delivery.

Ever since giving birth, I've been able to put my finger INSIDE my cervix. It hurts, and I've done it while cleaning. Sex has also been painful. I tried Googling it but couldn't find ANYTHING. Should I go to a doctor?
