If you dont mind share which vitamins you took? only Folic acid? Thank youHi All, i've just started trying to conceive and about 1mth+ back i started on a pre-conception vitamins. my period has been quite regular over the past 3 months all same cycle days. However its now late 39 days from first day of last period. i have no pregnancy symptoms at all or period symptoms except for cramps which i have been having on and off for about 2 weeks now. negative pregnancy test on 36 days from first day of last period. i'm just wondering if its the pre-conception vitamin that is messing my cycle up. have anyone encountered the same issue?
