Prenatal minus iron

Ti

So my iron is on the high side. I am currently taking Rainbow Lite Minis which have 100% daily iron and have been recommended to add in DHA and about 200mg of Magnesium. Told to switch to taking rainbow lite once a week and a different prenatal with no iron the rest of the time. Anyone have a recommendation for a prenatal that has all the fixings, plus DHA, minus iron? Might have to just get magnesium separately...
