Difference of opinions?

So my ob practice has 2 doctors. I absolutely love them both they’re sweet and they actually take the time with everyone. BUT my last appointment one of the docs said my blood work was fine I was slightly anemic but didn’t need to do anything. Today my other doctor (my favorite one) told me that I need to start taking iron pills for it. She said it’ll make me feel better and help balance my levels out but I find it weird that they told me different things. Anyone else have this happen before?
