anyone conceived after stopping the pill had withdrawal bleed but before 1st natural period??

[MMG21]

hi all, I was wondering if anyone has stopped the pill had the withdrawal bleed which is like a period. Then started trying before 1st natural period?? I had withdrawal bleed 22nd-27th Dec. Then based on flo app im due AF 19th Jan. I've DTF from 28th Dec to 8th Jan is it possible to get pregnant?? Or not because its not a true cycle? Any advice appreciated

@Rmd123 yeah its all a guessing game tbh I dont care if they wouldn't know many weeks haha id rather wait to have scan than wait for a BFP. If happens I'm gonna go for private early scan this time too xx
