Stormy

Hey ladies. This is my first cycle after first pp period. My son is 22 months. So I’m kind of shooting in the dark anyway since I’m not sure how long this cycle will be. And cycle day 15 for me. My Clear Blue advanced still says low. But the regular sticks are getting darker, almost the same as control line but not quite there. CM is getting stretchy... So shouldn’t this thing be saying I’m at least high? Bah! I attached today’s opk strips.
