Upset stomach after eating while pregnant?

Hey ladies, I need some input from you experienced mamas. 
I'm 10w5d and about 2-3 days ago I started feeling a kind of stomach pain every time I eat, pretty much anything. The pain isn't debilitating, it's just something I didn't have up until now in the pregnancy. Here is how it goes: I eat something, immediately food starts to get digested and I start feeling this discomfort on my upper stomach, followed by passing gas. Immediately after eating, which I find strange. Has anyone had this happen to them this early in pregnancy? I used to have a very sensitive stomach growing up and before pregnancy but after I got pregnant, the types of food that would upset my stomach no longer did (gluten, dairy and fried stuff). I'm thinking that my stomach is back to the way it was and I will need to lay off gluten and dairy again (I don't eat fries stuff)... although it doesn't seem to matter what I eat at this point, my tummy gets upset. I googled and learned that it's normal for this kind of thing to happen more commonly on the 3rd trimester, but I haven't even entered my 2nd yet... anyone has any idea? I plan on seeing a doctor soon because this is starting to worry me. Thanks a lot in a advance!! ❤
