Missed period

Katie

My period is two weeks late according to Glow. First day of my last was Aug 9th, lasted about 5 days. My cycles have been regular since March (when I got the Mirena out after 4 years of it being in) We haven't been TTC conceive very long but I'm just really stressing out about AF not coming. I've taken hpt like a maniac and got a faint line two days ago, and then negative this morning. Advice?
