Losing weight

Je

So, I’m ten weeks and two days. There were a couple weeks where I was ravenously hungry but I never had any morning sickness/vomiting. I’ve lost a couple pounds as I’ve noticed today but I don’t feel like I’m eating less at all. The only difference I can think of is I’m forcing myself to take a five minute walk after work (I work from home everyday) but that doesn’t seem that effective. Should this be concerning?
