Hi. I'm a FTM and I have tightening in my stomach that I've had for a couple hours now (it seems constant and it doesn't go away). I'm about 30 weeks. Yesterday I ripped up carpet and moved some light furniture from the baby's room with my friend and after I started having severe back pain. (I assume from over doing it yesterday) but now I started having this constant tightening with no pain (besides mild back pain) that won't go away. It started maybe 2 hours ago. Anyone ever experience this or know what this could be?
