Negative Test

Genny

This is our first cycle ttc. I'm 4 days late for AF, which very rarely happens. I tested yesterday with a BFN, so my hope for a positive is gone at this point. My breasts just started feeling sore today. My temp keeps rising. I'll test again tomorrow morning, but I don't feel anything other than mild PMS symptoms. Has anyone tested with a negative a few days after expected AF, only to have a positive later? Trying not to lose hope!
