BD September 15th and according to my other af app I was on my fertile cycle but glow said I wasn't. SO came more than once In me. I think my fertile is later in my cycle though because I had sticky cm about two weeks or so after bd which usually is a sign of fertile period (I've never had nearly as much of it as I did then). The sticky cm lasted for what seemed forever (four days). And it was quite heavy and embarrassing as I had to go to the bathroom several times a day to clean. I took a cheap test way too early (either 5-8 days before period)  which was negative but I could have sworn I could see a faint line a while later which was probably Evap I'm not sure. Sorry this is long.
