Loss of appetite?

Chris

Hi all, I just found out I was pregnant about a week ago, according to this app I’m about 4 weeks and 6 days pregnant. But I have such a big loss of appetite? This is my first pregnancy so I’m not too sure what to expect I guess my question is if this is normal? I don’t have much morning sickness but I’m just not hungry or when I am I only pick at my food and I get full but my body is still saying I’m hungry.
