I've been having some weird muscle spasms in my stomach for the past couple weeks (I'll be at 16 weeks tomorrow) and most of the time they are insignificant, but a couple of times they've left me breathless. I had one that made my entire stomach spasm and it scared me and my SO. just wondering if this is normal and if there's any recommendations on how to relax it. This is also my second pregnancy and I didn't have any of this with my daughter. Thank you everyone in advance <3
