Vaginal smell??!!! Help!!! 😖

So this is kind of embarrassing considering I’ve always been a rather healthy and clean person. Buuut recently (past 2 weeks) my vagina has been smelling awful, it’s not a fishy smell, but like a strong sour smell. My doctor said it was a UTI and gave me antibiotics which I took and I got a yeast infection so I took that pill, but this smell had been getting worse and it’s starting to make my clothes stink. There is a milky discharge and I don’t know if that is normal, but I thought I’d mention it. I do wear silk underwear and I do drink sweet tea and soda every now and then, but I don’t think I drink it enough to cause this.

I take showers everyday, I drink at least 40oz of water a day. I don’t know what it is. So please help.
