Lol I set my alarm.... I did stop for a bit cos it was getting stupid, I would do crazy things like waking up at 3 am to a beeping noise only to find the bbt hanging out my mouth I find it helps me know EXACTLY where I'm at though otherwise I have no clue. I don't get ewcm or o pains...... Usually the only way I know that I've O'd is my boobs hurt but I didn't even get that last cycle!
