Question for everyone! I'm 25 weeks and I've had arthritis for years, and for some reason the last few days has been really tough. All my joints are terrible achy and I've also been having a really tight feeling in my lower abdomen. I have an appt on Friday but didn't know if I should call my dr or not. Any advice??
