Has anyone tried going back on BC and then coming off of it with success?

Has anyone tried going back on birth control (I’m having some irregularities) for a couple of months and then gotten off it and received their BFP soon after?

I’m 9 days late with spotting only when checking cervix and haven’t tested yet with fmu but I’m highly doubting I’ll get a BFP this month due to my spotting. 4+ years ttc
