Four day cut off sounds like girl territory to me!!
I haven't done any PH testing and don't plan to either but the fact that 4 days away from O sounds like a good way to go!
I do hope you get your BFP in the next couple of days. How's your temp chart looking? Is it still staying higher than the beginning of your cycle?
Did you do diet or supplements for girl? Did your other half wear tight pants leading up to bd?
