I had 6 hours of regular pains which at first I thought were Braxton hicks til they became painful, pain was mostly in my back but eventually spread to my stomach, they came every 3 or so minutes, I had a lot of pressure down below in the front and back, I was put on a monitor which showed these pains, all other obs were great, had a speculum and an internal a which showed my cervix closed, for the doctor to then say it was SPD! Do spd pains come and go like contractions??? I was given codeine and sent home where they eventually faded after another hour, is this really spd? I'm just not convinced these tightening match what I read!
