OBGYN had me start the pill again to help get pregnant?

So a while back my husband and I were going to start trying. My OBGYN got me back on the pill WHILE taking prenatal vitamins in order to regulate my periods so that once I stopped the pills, my body might be regular enough for a few months so I could get pregnant.

Well we didn’t start trying back then. I’m still on the pill. No prenatal vitamins.

But now we plan to start trying in December. I’ll start taking prenatal vitamins in September.

So, had anyone tried this method?

My OBGYN has said “there’s no proof that BC pills make it harder to conceive. There’s a reason you have to take a pill every day.. it’s only in your system for a day”

TIA
