My wife became prego about 7 months ago and ever since she smells sour down there. I havent went down on her since she got preg but I can smell it on my hands and shit big time after we have sex. Even after washing my hands that shit still stinks. Before she got preg it tasted and smelled like roses. I would go down on that shit for hours. She has had issues with having yeast infections since she got pregnate and she treats it but it smells bad even after she treats it. God I hope its just the pregnacy or Im going to be ruint.
