Been feeling bad since last night

Idk ladies I’m 30 weeks and I feel terrible. I’m short of breath all of a sudden. It’s like it’s hard to catch my breath esp when laying down. I feel so weak and I keep getting these shooting pains through the front of my stomach where my belly button is. Baby is moving just fine. I just feel so

Weak and it’s literally all of a sudden. If jay started last night. Do anybody know what could be wrong? I’m trying to avoid the half hour drive to L&D. I have a doc appt on the 29th as well.
