Been TTC for past 2 and half years and used Pregnacare Conception but I picked up just an OTC Folic Acid from Boots this time as have lost all faith that even helps to be honest! Been taking it from the point of ovulation and now I am 5 days late, when usually I am every 28 days cycle... Is this caused by the Folic Acid supplement or should I dare take a pregnancy test?!!
