Pregnant iron infusion

Just wondering if anyone can give me some opinions

So I’ve been on iron pills supplements because I was low on iron well on Monday my doctor said I needed iron infusions cause I was still low so the next day I went and got one I’m not sure the amount they gave me but it was like a 45 minute drip she ordered 3 infusions one a week so next week I go for my second

Well anyway I forgot to ask her if I should continue to take my supplements as well or not anymore so yesterday I skipped it and called them but they never called me back so today idk I should skip my supplement again or just take it ? I get so paranoid skipping them especially since I’m having twins that share a placenta I’m just paranoid if I skip them something bad will happen to them and I usually take my pill at 7 that’s the way I’ve been doing it and they don’t open till 8:30 so idk what to do 😑😑😑 any input on this ? 😒
