Yeast Infections and Natural Remedies

I've posted a question recently but no one has answered yet. So I'm going to provide more information. I think I've been suffering from a yeast infection for about a month now. Around Oct. 3 I started having the abnormal discharge and burning sensation in my vagina when I Pee. However, October 12 I got my period and the burning sensation went away and obviously I couldn't tell whether there was still abnormal discharge until after it went off. I did read that menstruation helps pass bacteria out of the vagina(don't really know if that's accurate). Anyway, after my period went off, I began to have full force itching in my vagina and on the outside, but no more burning sensation when i pee. The discharge had no odor and was white. Now it has an odor and is more yellowish. I need help with figuring this out. I was certain that this might be a yeast infection, but I don't know anymore. It might be Bacterial Vaginosis or Trich from what I been reading. The symptoms are pretty much the same for all 3. It is easy to say go to the doctor, but I don't have insurance so I don't know what to do.

I tried using an antifungal cream but that made my itching worse and my vulva swelled. So I didn't even use it the full 7 days. I've tried the sitz bath with vinegar and salt. That helps temporarily. I've been taking acidophilus pills which has been helping alot with the itching, but still have it a little. I'm thinking of trying garlic vitamins and tea tree oil. I'm also going to buy some plain yogurt. I just want to know does anyone have any other suggestions regarding natural remedies. Thanks!
