No judging

I just had a baby almost 8 weeks ago, and before I got pregnant my appetite was really good it was normal I wasn't overeating. Then once I got pregnant, a little bit I was but only gained 20 lbs though and I lost 16 lbs. After I gave birth... everything changed. I had no appetite I had to force myself to eat every single day and I still do, I just can't even eat I don't even feel hungry and when I do eat/don't eat I feel so nauseous so matter what. I don't know if this is normal or not.
