Help please

So I have been on glow now for about 2 mouths and I'm always getting these things to do in the morning and one of them is to take prenatal vitamins every day but my question is on how does this help me to conceive ? And if there is a wrong kind of prenatal vitamins to get? I did pick me up some and I want to make sure it won't harm me or that I'm not taking the right ones? These are the ones I have picked up today please help me I want to make sure i am doing everything right. my husband and I have been trying to conceive now for two years and this is my last hope till I go to the dr and see what else I can do.​
