My doc prescribed PreNexa and I've only been taking them for two days (i know, i know...I should have already been taking them but I didn't). I don't have much to say about them except, wow are they doing some crazy things to my stomach. I am only 5 weeks and so far I haven't experienced any sickness (hoping I dodge that bullet) but these prenatals are making me run to the bathroom for different reasons! Especially at night! Can anyone else relate?
