rebirtha: Guys, just took another OPK and it was negative! Am I too late??? DH coming home in an hour! My cervix seems a little harder too. 
WHAT?!?!?!?! That's crazy! Are you sure you held your pee long enough? Have you been doing all the crazy drinks this morning and maybe it's too diluted? What about your CM - still stretchy?? If so, I'd go for it. Don't worry about CP, you said you just found it anyway, right?
ETA: My pH is up to 5.9 today! It looks like a 6 on the paper strips, but I'm trusting the digital. Woo-hoo! I know that doesn't seem like much to everyone, but it's a VAST improvement over my usual 4.5. Even if I have to use BSF to get it up higher, I'll still feel good knowing I changed it so much w/the ACV (I really think that's what did it in the end).
