crazy hungry all the time

C
Any nursing moms getting crazy ridiculously hungry every day?  I'm 9 weeks and 3 days PP.  I eat tons and still hungry. Not gaining weight (not that I'd want to).  Not sure if this is due to nursing my sweet baby girl?  I had an IUD put in a few weeks ago and heard that can cause hunger too.  So just seeing what the norm is here. I'm a FTM. Thanks!
