Eating habits?

Just curious...my 1st trimester I had super strong hunger pangs even with nausea and I would have to eat like every 2 hours. Now that I’m in the 2nd trimester I rarely get hunger pangs and when I do eat I find I get relatively full fast. Sometimes I even make myself eat because I know I have to, not because I’m actually hungry. Just curious if anyone else is experiencing this?

My 16 week scan showed baby girl measuring in the 30th percentile so I’m just anxious about making sure she grows.
