Help!

Kristina
AF should have arrived 10/17, but has yet to arrive. I've had symptoms of her arriving on and off but nothing. I took a HPT on Saturday and it didn't show the second line (that I could see lol).... I'm confused because I'm typically NEVER late. Should I test again? Could it have possibly been too early to tell? We've been trying for over a year and this is so frustrating to me !!
