I know what it is, I know what it looks like, but I don't understand the timing of things. I know lovely young fertile girlies will have approx 5 days of it, and as an old chrone (38) I usually only have a couple of days, when in that couple of days do I ovulate? I can't temp (shift working, irregular hours and nights) and I know I should really go out and get some OPKs just to see when I ov, but until then please tell me how it works. I presume as the egg only survives for approx 24 hours after ovulation, that you stop producing ewcm 24 hours after ov, because there's no more need for it. Is that right?
