no appetite

My sweet baby was born on the 30th and I am EBF. Ever since delivery I have had a lack of appetite. Now being home for a week there are times when I realize it has been way too long since I ate, but literally nothing sounds good. Anyone else experiencing this? Makes me nervous bc it's on the list of things to watch for with PPD. I feel like everything is going well and the ups & downs I have are just normal....
