post ovulation shed

Well, everything I've read says the post ov shed is about 16 days after ovulation...how accurate is that? I have two girls who went on the 22 and 23, and neither has shed, yet, nor went in the blue. Based on the 16 day thing, they should have shed on the 7th and 8th. So I'm just wondering if is this common or uncommon :confused:

One thing you will learn about BPs, they never go by the book ;) Patience is the key with these guys. If you really saw an ovulation it should be happening any time now. However, some people have mistaken a big build for ovulation so that's always possible...
