30w exactly and had my appointment today. Perfect appointment. Strong heartbeat, felt great, cervix is closed but has shortened by half. Since about 3:30pm my stomach has been tight, she's been moving like crazy off and on and I can't seem to catch my breath to save my life. I'm constantly deep breathing every now and again because I feel like I'm not get enough air. 
I've been drinking water like I've been stranded in the desert. 
I'm having BH (which are my normal routine 😑)
Is this normal? I'd hate to travel to l&d which is a 30min drive. 
I just want some relief
