No appetite

I've been meaning to ask this for the past 2-3 weeks anybody else been through this??? every since I had baby I have absolutely no appetite everything looks gross smells gross just like when I was pregnant and I'm not really complaining because it's helped a lot with the weight loss I lost all my baby weight plus some but now it's starting to bother me a little bit because I'm getting headaches from not eating and I'm like living off coffee
