Took day 2 of my placebo pills but still not bleeding. is this be due to bleeding i had for a week from irritation from acv bv treatment, could i be pregnant, or my bcp? sex + bv happened 2 weeks ago.

Might be normal: Assuming that you missed no pills, and knowing that when you are on the birth control pills, your cycles will become lighter, then not having your period just 2 days into your placebo pills might just be normal. I would check a pregnancy test and contact your doctor if you do not get your period by the time you are ready to start the next pill pack.
