This has been the worst pregnancy ever, my body feels like I have the flu. I'm literally aching from head to toe.. my joints hurt the worst. Then on top of it all I have so much pressure in my vagina it hurts to sit up straight or use the bathroom. Do any of you guys know anyone who has carried triplets or carrying them. I don't know if I should be worried or is this just how triplet pregnancy goes??? I've been pregnant two times before this an I've never felt this pain....
