Bacterial vaginosis??

I had a ph imbalance so I went to Wal-Mart and got a otc for the odor and balance , it was a 6 day treatment, on the 5th day I gt a yeast infection , started a 3 day monistat treatment , had to pee and it burned super bad went to the hospital asap , they couldn't tell me much but treated me for bv I've been ttc since September jus finished the antibiotic metronizole that was prescribed no odor or anything :) my question was anyone get pregnant after getting rid of bv? Do u think bv was in the way ?
