Yeah sorry, I should have said I had 3 a day because i'm usually amemic anyway and this makes up for the amount you make for babs too, you only have 3 if it's really low. Ring your midwife or GP and they'll have it on record from the hospital that you are taking them and should tell you the dose, I don't think it's possible to over-dose, if you did you'd only get constipation and a bit of sickness, after my son was born i was on 5 a day!!!
