The mystery continues...

AF is still missing in action and the Boobs are very very sore, but the HPT still shows only one line. What the hell is going on? We did some baby dancing on Friday night and afterwards I noticed some light spotting. I thought AF had finally arrived, so I was a little disappointed but got into bed and forgot about it. The next morning I expected to to see a full flow, because I felt some cramps during the night, but I was quite surprised to see that there was no blood whatsoever. So this morning I did a HPT and it still showed negative. I don't know what to think anymore. I am a bit scared that my PCOS has gone haywire again and that my cycle is totally out of whack again. I guess I'll wait and see for another week and if AF hasn't arrived I'll go and see Dr F. again. Any of you have any better suggestions?
