Terrible stomach ache for days

I’m 7 weeks tomorrow and I’ve had a terrible stomach ache for a week straight. I force myself to eat breakfast lunch and dinner but it hurts so bad after I eat. I was eating a lot now I’m not snacking at all just eating my meals. Is this normal? I feel gassy and tmi but can’t poop 😭 I didn’t get sick at all with my first pregnancy with my son so I’m seriously hoping I feel better in the second trimester
