I need opinions.. HELP PLEASE!

So... I'm TTC & am currently on BC pills. I'm still fairly new to Glow so I'm not sure how all of this works. I originally got on the pills to try & stabilize when AF visited, but I tried to make sure that I didn't take them when glow said I would be ovulating. My partner & I had intercourse every day I was fertile & I thought I was starting to have some telltale signs of implantation, yet yesterday AF came to see me even though I wasn't supposed to see her for another 9/10 days. I had taken two PTs & both came up negative. Do y'all think I could be & its just too early? Am I not? Or do you have any tips to try & almost guarantee conception? Please help...
