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. 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 cheap little test this morning when I first woke up and it said negative but still no period. I’m usually clockwork so idk what this means. Help?! Thoughts?!
