Prenatal vitamins questions ?

Felicia • 👑
This is my first time being pregnant 😓 it's a little nerve wrecking . But I have a question that might be kind of a dumb one , but bare with me . 
. I'm about 4 weeks , I haven't gone to a doc and I haven't told anyone because I haven't told my husband that I'm pregnant (waiting to surprise him in a week for our anniversary ) 
So let me get to my question .
I just bought over the counter prenatals , and there is two sets of bottles with two different pills One says Dha and the other multi . 
I just wanna know , 
am I supposed to be taking both pills together ?
