I am new and I new advice.

Courteney • I am a 24 year old wife and SAHM of 3 kids. I am a geek and a bibliophile.
I haven't had a period since April of 2010. Since then I have been pregnant 3 times, breastfeeding or on birth control that prevented me from having a period. I am currently 4 months post partem and breastfeeding my third baby and I need to know how to input that information into this app.
