How much are you ladies taking? I saw my OB the other day for the first time (I'm 6 weeks today) and she said she likes more "mature" expectant mums to take 5 mg per day. I'd been taking 0.4 mg (as I did for my entire last pregnancy when I was 35-36). She prescribed me a special prenatal vitamin which I'm now taking. Now I'm trying not to stress about having not taken a higher dose earlier. I'm not trying to worry any of you--doctors are notorious for disagreeing about such things--but thought I'd pass on the info anyway.
