hi prenatal are for when you get pregnant. but getting pregnant is all down to timing timing works like this with your cycle day 1 is the first day of your period around day 14 is ovulation day or the day your egg drops in to your womb so you need to have unprotected sex around 5 days before this it takes male sperm 3 days to reach your womb they can then live in there for up to 10 days max so by having sex when i said there waiting for your egg if this works you should get impletion spotting around day 21 if this carries on and you miss your period you then do a test hpt or get a test done at your doctors if positive you can then take your prenatal vit's. do hope this helps you. good luck ps try not having sex to often other wise the sperm will be immature and this will not get you pregnant.
does taking prenatal vitamins help with fertility/ conception? . i'm trying to get pregnant and it's taking a very long time i just want to boost my chances of conception a little i've been off the pill for 6 months now.
