Well the 'signs' I never get in any cycles. I do not PMS or anything before AF comes. Normally its a headache and then the headache disappears and AF is here, so I dont have any warning at all! So the achiness and tender boobs makes me think that maybe something is brewing

And my temps could be just what my temps do. But yes, the next few days are the most important cause my temps could either rise or crash & burn!
