Hi i'm 34 yrs of age, i'm trying for the baby for a year now...i started to take folic acid & feminine herbal complex from last month now i'm 4 days late on period which is something never happend to me before, i don't have any sign that i'll see my period or cramps or swollen abdomen which is what i go through every month before i get my period...should taking folic acid & feminine herbal complex delay my period?
