Just a little concerned.

So I'm 12 weeks POstpartum. When I was giving birth to my daughter her shoulders got stuck and they had to cut me. And the after doing that I tore and had to have surgery to be sown back together. I went to my six week appointment and the doctor said everything was okay. My fiancée and i tried to have sex The last couple days and it's okay at first but then it really starts to hurt me and it starts pulling. Almost like I'm stretching out. Is this normal? Do I need to get it checked out? I just don't want anything to be wrong. Very paranoid and nervous.
