Am I overreacting? Should I be working?

I am 8 weeks pregnant and I think I have IBS (if anyone on here does have it and this doesn’t sound right please lmk, I haven’t been diagnosed). I’ve had these stomachaches and issues my whole life, but generally I’d get them a few days a month, maybe more, so it didn’t really interfere too much with work. But for like two weeks now I’ve been getting them daily, once or more often. They come randomly and I never know how long they’ll last or when it’s going to happen, so I’ve stopped going into work out of fear that it’ll happen while I’m there (and it has before).

I know it probably doesn’t sound that bad but these stomach aches get so bad it reminds me of being in labor. When I get them I try my best not to react in pain but I can’t focus on anything or do anything, and then they send me running to the bathroom with diarrhea. My work doesn’t have private bathrooms either.

So I guess I want to see if I’m just overreacting. I see so many moms with morning sickness still going about their day fine and I’m at home because I’m scared of when the next stomachache is going to hit me. It wasn’t this bad with my son. It did get worse during the first trimester but it didn’t happen daily.

Oh, and anybody with IBS (if that’s what it is) do you have any advice? I don’t want to be scared to go to work.
