So is it possible to conceive 4days before ovulation ?

I don't believe so, the egg wouldnt be present

no its not possible u have to ovulate first when the egg is there.

it's possible to even conceive while on your period. anything is possible

I conceived the last day of my period. So I mean, yeah lol

ovulation dates aren't an exact thing. just estimated based on your periods. but just like everyone's period is different, so is there ovulation cycle

so you could have been ovulating 4 days prior

yes it is! plus sperm can m 've in you for multiple days!!!

I conceived the day after my period ended
