Still sore 3 month later

My daughters birth was pretty rough, her oxygen levels kept dropping and we rushed to get her out before I was fully dilated. I had two internal tears from forceps, and one external. It was to the point that one of the 3 doctors who was working on me told my nurse to call down for A+, thankfully they got me stitched up before I actually needed a transfusion.

I was cleared at 10 weeks postpartum to resume normal activity including sex, and she said she’d see me back in a year.

Only thing is that it’s been 3 months and sex is still uncomfortable, especially when my husband is behind me (it’s his favorite position so we try it often but he stops as soon as I tell him).

I was wondering if anyone else had experienced internal tearing and how their healing process was. If they also experienced this, what they did, and if it ever went back to normal.

(I have spoken with my OB, currently she just wants me to wait it out)
