I am 39 years old and have regulary taken birth control pills since my second and last child was born in 2002. During both pregnancies I suffered excruciating pelvic pain although neither of my obstetricians seemed to understand my condition. But after the birth of my second child it totally went away...until this morning when I arose out of bed with that same debilitating pain. I finally googled it and found out it was SPD but it's always associated with pregancy. If I am pregnant then I have been totally unaware of it as I've always had horrible and early onset of morning sickness that always lasted throughout my first trimester. What is going on?
