Cycle buddy?

Danielle • 33yo, first time mom and so excited for it all!! Married 10.03.2014 and we are over the moon about our Nov baby boy!
I'm new... Curious about how cycle buddies work. 
I'm due for my cycle to restart today... 
Thanks for any info... I'm new to this world and am very excited.
I'm 33yo and am ttc baby 1. Got married October 2014 and have been with my DH for about 5years. We are so excited for this new journey.
