8 weeks - are these normal signs ?

I’m 8 weeks and lately I just never feel good. I’m nasceous all day, gas pains and I know that can be normal but what I’m worried about is my stomach just never feels great - there’s a dull pressure low down and it always feels bloated and sore - best way I can describe it is that it feels weak like after an ab workout but as low down as the underwear line is the area I’m talking about. I also had really bad diarrhea this week twice after dinner. I’m worried - are these things normal esp the stomach weakness and tenderness
