Friday the 13th-miserable week

Creepy, superstitious day, true, but it's when my AF is due. I tested yesterday, then again today, and both have come out negative. I have had NO sign of AF, as usually I would see some spotting by now. Trying to be patient and not reading too much into symptoms. To top it off, I went to the doctor and found out that a cyst just decided to come out on my lower back, so I am also in pain!! Taking stuff for it, but in a bad mood. Sympathies/ hopeful words, anyone? :-(
