When you have your first doctors appointment they should give you a bunch of different samples to choose from. They all will be good just find the one that works for your body and order a prescription :)
Also if you have trouble keeping them down then take them at night. That's what I do
The easiest ones to keep down are the gummies they do pretty good but if you can't keep those kind or regular prenatal pills down! Take 2 flintstone vitamins a day and it equals to 1 prenatal! Congrats!:)
I have Pregnacare Max. :)
They have folic acid, vitamins D, E, K, C, B1, B2, B12, B6, B3, Fcolic Acid, Calcium, Iron, Zinc, Copper, Omega 3 Fish Oils with added DHA. They are the best ones you can buy in UK but slightly expensive.
