seems to end before it began

So excited about the IUI, went for baseline US and discovered a cyst on ovary!! Might have to cancel!! Nurse was supposed to call me back to let me know! Low, and behold she never did!!!!!!!!! I am so upset that things seemed to come together, then this happened! I am so frustrated!!  I'll find out for sure tomorrow!! Lord give me strength because I am tired and discouraged!
