Problems after delivery/birth control?

Today I went for my postpartum checkup. I ended up having to go about 2 wks late. But anyhow, I had a 2nd degree tear. My ob said it looks like I have some tissue from where my laceration is trying to heal. She put some medication there and it burned. She said it would make it heal faster, and that I could be intimate w/in 2 or 3 days with my husband. But I won't be doing that anytime soon. My left side of my has bene hurting since I had my baby, and I think that is where I tore myself. She also gave me a pap smear. I have also been leaking urine a little. All she told me to do was do dome kegel excercises. But I have been doing that since like before I even got pregnant. She was not helpful at all, and she was like in a rush. And my left side of my l area is more painful that it was when I went in. I also told her when I sit indian style, I get pains in my roal/labia area. She did not offer any answers really. Will this pain that I'm feeling go away?? And will I stop leaking urine?? And she also said that since I'm feeding my baby, I really only have the choice of a mini pill or mirena, but I have to wait for my pap test results to see if I can try mirena. Which would be better?? I've been reading up on IUD's and I'm not sure if they are something that I would be comfy with.
