Little to no appetite

Any other moms out there having a hard time getting themselves to eat?? I am busy and tired most of the day but when I finally have a minute to cook or eat something, nothing sounds good and all food just sounds unappetizing. I NEVER have this issue lol I'm a big eater! Baby is gaining and I have plenty of milk, but am definitely concerned she is not getting as many nutrients as she could - and I'm selfishly thinking my lack of calories is gonna cause me to hold onto this extra weight for BF! Just wondering if this is a common thing or maybe just a slight hormonal/postpartum mental thing.
