Discharge

I've always had a constant discharge that smells and changes in color from time to time...sometimes a light brown, to a creamy white, even yellow, which is most of the time. Does anyone else have this? I always ask my gyn about it, but she says it's not an issue and to take probiotics or eat yogurt if I want. It'd just be nice to know that I'm not alone in this... I always get embarrassed when it comes time to get intimate with my hubs! Granted he knows about it and (bless his heart) doesn't say anything about it... But I still get so embarrassed when he goes down there!
