“Question about an iron supplement?”

I just have a quick question about what I can take with my iron. I take ferrous sulfate 325mg for my anemia, but I also have endometriosis. I used to take cranberry pills and I noticed it helped in some senses, but I’m a bit nervous to take it with my iron. I tried calling my doctor but she won’t call back, so is it safe to take a cranberry vitamin with iron? I made sure my cranberry pills have no calcium in them since that can interfere with iron. I take a b12 along with my iron so is it safe to take all 3 together? (I used to take the b12 and cranberry together.) I tried googling this but didn’t really get a yes or no answer / the answer I was looking for. I know it’s probably safe but I just want to be on the safe side.
