I definitely notice the the temp rise, black. I am always freezing, my hands are ALWAYS Cold no matter what and my usual temps mid day are usually in the mid97s. After O I feel uncomfortably warm, almost feverish, and even my hubby will comment on how warm I suddenly am (versus complaining that I'm too cold to touch lol!).
So, the last several months I O'd on the day of the +OPK but not convinced that'll happen this time. I know they say sperm lasts 3-5 days but is there a number that is standard ? Where is the cut off line, like most are 2 days but some are 3 and a few are 5? Or what? I dunno why I am stressing but I just wanna get the most chance possible. if we BD on wed and if I were to O today that's 2 days. So would that be a chance?
Like black said, if I don't BD within a day or 2 of O I automatically feel out.
