Iron Pills vs Prenatal Vitamins

At my last appointment I was told I was anemic (iron was 9.9) they prescribed iron pills for me to take. I was told to take them on an empty stomach and also to take them with my prenatal vitamins. The thing is though if I take my prenatal vitamins on an empty stomach they make me sick and I throw them up. The first week or so I took the iron pill and prenatal vitamin together as recommended and I kept getting sick. Not even a hour down and it’ll come back up. So I decided the next time I took them I was going to take them with a little snack not a whole meal. Just something heavy enough to where my stomach won’t be too empty. I did that , and to my surprise they came right back up. At this point I don’t know what to do. My doctor told me to keep taking them but my stomach just can’t stomach them both. So I decided I take them at different times , iron tablet in the morning (considering I be up at 5 because I have to be to work by 6) and I take the prenatal at 10 at night before I go to bed. That’s working waaayyyy better than taking them both at the same time. But sometimes well majority of the time I forget and end up going 3 to 4 days without taking the vitamin. Is there any other way I can take these without either forgetting or getting sick...I need help because I feel like I’m cutting my baby health off.
