I still watch it here and there. I am amazed they can film that!
I remember that PBS film and it was great. I didn't save it and was looking for the link but I'm glad you posted the name so that I can find it again.
I would bd. I get ewcm for 3-5 days leading up to o. It's possible you may o early or you may just be getting ready for normal o time. Ewcm can keep sperm alive for several days then once you o the cm becomes watery letting them travel and they are ready to roll :) If you haven't watched it yet, there's a show on the PBS website called "Life's Greatest Miracle". It's under the Nova programming. They have actual footage of the sperm trapped in the ewcm and then show it changing and making little channels for them to swim in. It's truly amazing to watch. Someone posted it about 6 mos ago and I saved it and watch some of the clips from time to time. I still don't know how they got that footage!
I got EWCM and O'd early. I started testing with OPK kit. (this was last month) It was pretty unusual for me to have a 21-day cycle. I, however, think, my cycle was screwy because the prior month I had taken the meds for IUI.
Go ahead and start BD'ing. Can't hurt, right?
