Painful Intercourse

Kaitlin • Wife to SB. Mommy to PB and LJ.
Hello all. For the past 8 months or so, I've had painful intercourse. Only when my husband goes really deep and during doggie style. My gynecologist and regular doctor said they didn't see an infection. However they never gave me a blood test or ultra sound or anything. Does this happen to anyone else? Some days it doesn't hurt as much as others but it is quite often. It almost feels like he's hitting one of my organs, lol. I appreciate the help!
I was told I had a bladder disease called interstitial cystitis. Which is supposed to cause painful sex, however, I urinate right before sex and empty my bladder and I seriously don't have any of the other symptoms associated with interstitial cystitis. I don't have just normal pain or bladder pain. I just have the urge to urinate often.
