Usagi- actually when u see yr gynae next week, can check with him if can start on vits.
Luvnhope is right. First trimester, folic is enuf. Just need to take some healthy meals eg fish, veggies, fruits, proteins.
Start of second trimester that is where u start all the vitamins prescribed by doctor.
Think of it this way - first trimester is to stabilize. Second trimester is to 'bu'.
And not to forget, drink lots of water.
