How long can they go on for and when do they occur? I've had a tugging type dull ache yesterday and today, but AF is not due until 29 January. I ovulated on 16th January and we DTD on 9, 11, 14, 16 , 18 and 19 January.
I have a regular 28day cycle so I can't believe AF is coming a week early - dare I hope it's a good sign?!
