prenatal vitamins

Okay so I'm 10weeks and for about 13 days I've been none stop nauseous were I have to force myself to try and eat something for the baby I take my prenatals everyday till my co worker said it could be your prenatal making you sick. So I stopped taking it but only for a day and it helped so much but I'm nervous now cause I know the baby needs it please don't hate on me or anything but what should I do
