I Have Been Going To A Hematologist The Last Few

I have been going to a Hematologist the last few months for low iron (ll.3) , my Feratin count is 15 and for low white blood cell count (3.6) . I am thinking about getting another opinion from another Dr. because this has been going on since December, and although I am feeling fine, the current Dr. has me taking additional iron but just has the wait and see approach. I have had blood work done every 4 weeks. Your thoughts?
