Cyst!?!

My cyst is still here. :( I can tell because it keeps throbing and tingling. I keep hopeing that when it does that it means it is bursting but then the next day it tingles again. :( I called the OB to find out when I could do the S-HSG but I have to wait to call till AF comes. I have no idea when to exspect her. If were going off how long my cycles normally are then she should be here Tuesday but I would be willing to bet money she will be late.
