Sex still painful please help!


Hi ladies hoping there might be someone out there who can offer some advise as I’m still suffering from painful sex and my OB is stumped as well. I had a c-section in Dec and ever since I’ve had burning and extreme discomfort in my vagina anytime we’ve attempted sex. She’s tested me for any type of yeast or bacterial infections and nothing. I’m now on estrogen cream but that hasn’t helped yet either. It’s super frustrating to not know what is wrong. We’ve tried lots of lubrications as she’s also suggested it could just be extreme dryness from breastfeeding but I just know in my gut it’s got to be something else. I normally have a high pain tolerance but this is just so uncomfortable and frustrating. Thanks for any advice anyone can provide!!
