Help!! I need input

Sami
My last cycle started January 28th! My cycles are so irregular! We have been trying to conceive baby number 2 for 1 year. I feel crampy, been extra gassy, hungry, and just flat out feel like I'm pregnant. When should I test?? I'm so impatient but don't want anymore negatives! One app says AF is due the 25th, 28th, and another says March 2nd! Any input is greatly appreciated!!!
