So uncomfortable

Im 25 weeks now and my stomach is just always irritated.. I’m gassy, bloated and as of this morning, I can’t use the bathroom. On top of it, I have no appetite, when I eat I feel full very quickly and I usually end up with heartburn, nausea and acid reflux.... Please tell me I’m not the only one! I feel like there’s a brick in my colon that will not move. Sometimes my gas pains are SO BAD. Is this pregnancy or something else? I’ve had ibs-d for 3 years but I’ve never experienced this before.
