Vaginal discharge and odor

So I’ve had this vaginal discharge that’s clearish white and it has an order! Like onions!! For Years!!!! Practically all my life! It’s so annoying! My GYN says it’s nothing and that i just need to take probiotics, drink more water and watch what i eat! They’ve done all types of swabs and they all are negative! No BV etc... Does anyone else have this issue! I feel like it’s something more because this can’t be normal and could be as to why i haven’t conceived baby #2!
