3 month pack is done will it come back?

I am days away from my first monthly bill after being on the pill for 3 months straight.I had a brief itch down below and thought wow is my bv going to come back and I need to update my fellow friends who are fighting bv. I am going to take extra precaution by using rephresh tonight so my ph levels will be balanced before it comes this coming week. I have had success with the pill! No bv for three months!!! Now is the test,let's see if it still has any affect even though I still get my period. Once I get it I'll be back on my three months of not having one. I will report back!
