Am I?

Today makes it Day 3 without my period. I have cramps in the lower area of my stomach & for some reason the pain shifts. Like sometimes it’s on my right, left or in the middle of the lower area. I’ve had more appetite than usual, very moody, frequently going to the bathroom, feeling tired, headaches, etc. Is this what I’m thinking? I’m tired of taking tests, because we’ve been trying for a year now.

** My period is always early or on time. Never late.
