Hun I'v just posted in your other thread but I wanted to offer you another . With my stillborn son my lochia lasted 3 weeks and I got my period back at 6 weeks to the day. Each and every woman is different though so it's hard to say.

Regarding the pain and stinging, I'd suggest getting a check from your ob or midwife babe. Just to make sure it's all ok.

HTH
