Ttc help

Payge

Ok I’ve decided I need some insights. I had taken a break from Ava, the groups, anything ttc and just lived my life.

Here’s where I need help. We BD’d June 26,27, and 30 which just so happened to fall in my fertile window. I was still using opks for my fertile week and peak day was the 30th. We went on vacation and didn’t worry or think about any of it. I was supposed to start my period this past Friday the 16. My periods are usually 3 days. I have yet to start. I took a FRER when I first woke up and it said negative but still no period. I’m usually clockwork so idk what this means. Help?! Thoughts?!
