Why am I not eating like i used to

Nicque

I am 6 weeks 2 days. During the first couple of weeks i was very hungry (more like starving). I would eat every 2 hours. Now i can barely finish a small plate of food. I feel really bloated and fatigued after i eat a little bit of food.. Has anyone else experienced this? Is it something i should talk to my doctor about? I've been drinking Ensure just to make sure im getting enough calories and nutrients everyday
