Period games....

Haleigh
So my hubby and I are not TTC, but would be happy if it happened by surprise. My period is now 6 days late (not a normal thing for me) No symptoms as of yet. 2 negative tests so far. Nothing has changed in my routine, so I'm not really sure what's going on. I plan on scheduling an appt with my doctor. Does anyone have any advice or similar instances?
