Prenatal vitamins help

So I am 20 weeks pregnant and have not been taking my prenatals faithfully. The ones my doctor prescribed me are so gross that I feel sick when I take them. It’s the kind where you have to chew and swallow it but its not the sweet gummy kind. They are these chewable tablets and I hate the way they taste, they make me so nauseous. I need advice how to take them and what kind do you take?
