It just won't stop..

Since February 11th, I've had nine days with no bleeding. Nine freaking days. This is so weird and I've gone to urgent care and the hospital and everybody keeps saying that it'll stop. It hurts so bad, it feels like my bones are breaking over and over.. I have PCOS and hypothyroidism and take medication for it also. Last night, I noticed that my nipples have gotten bigger, my breasts feel heavier and I can see veins all throughout my breasts and my nipples have been so sensitive and sore the past week. I just don't understand why this all has to be so confusing..
