Leesa, the cycle before I fell pg I had a "phantom pregnancy" - a 23d luteal phase, 55-day cycle, sore breasts, nausea, off various foods and stuff... just as I started to get my head around the idea that I may be pg and should do a test at the weekend, AF arrived (drat her!). And she stayed for a full week, not her usual 5 days! The good news is, the next cycle I had I did get pg, but had nowhere near the amount of symptoms I had the previous cycle!

Looking at other replies, it would appear a phantom pregnancy is quite a good sign!
