Upper abdominal cramps after eating!! 5 weeks

I am around 5-6 weeks pregnant, we had a miscarriage a little over a month ago and I got pregnant again without a cycle in between. Over the last 5 days I’ve been having really bad cramps in my stomach, upper abdomen after eating anything.. it feels like a gas pain, and everything in my abdominal region is tight. my doctor said it could be my bodies version of morning sickness, but I’m super stressed as it sometimes is pretty intense and we are going on vacation on Monday for a week! Has anyone else had this issue? Thanks ladies
