I am 29 weeks pregnant & the last few times my husband & I try to have sex it hurts almost a burning sensation. I told him it felt like He was rubbing on something. He said he felt it as well so placed his finger in there to check and he said my bone was pushing down hard inside my vagania. This has never hurt before and never been noticeable. Does anyone know if this is something I should be worried about and to call my doctor?
