I was on my feet all day cleaning, washing floors, and at 2 am I called an ambulance because my left side started hurting. It felt like ligaments were pulled (they put him in the hospital, CTG 190 for the baby). Do you think this could be related to fatigue? He was very active until 6 am because I didn't sleep for a whole day and a night. Then I slept for 2 hours and it got better. A week ago, the CTG was normal.
