I am 27 and 12 days late on my cycle (several pg tests negative) and woke up the other night with the most horrific pain radiating in my lower right back. It went away after a minute, but ever since then I have been getting more suttle pains of the same kind in my back, shoulders, lower abdomen, legs, vagina, and less often in other places. I feel as if an ovarian cyst is the only answer because I have had small ones before (along with endometriosis and adhesions from c section) and I usually don't just miss my period for no good reason. I feel like something is poisoning my body, could it be a leaky cyst? I also have had unexplainanle microscopic hematuria in the last year or so, could this be related? Any advice until I make it to the Dr. is apperciated.
