So today my tummy and pelvic tightened up for. ,2 and a half hours not easing up at all!!! Finally started tho ease up afterwards now my sides and tightening up again but not as bad. This was making me almost cry. My hubby says it's just my muscles getting ready for baby but I'm not sure that was a long straight time but who knows. What do u ladies think? I'm 25 weeks.
