First day off BC!!

Amy • Married 5-20-12 to my love since `08 ❤️ Our 🌈 Lucas arrived 5/16 - baby #2 became an 👼🏼 in 9/19
I've been in the pill for 12 years, and today was my first day off the pill. How long does it take for your body to adjust to going off the pill and acting 'normal'?
Hubby and I want to start TTC, and I haven't had a period since January because of my BC (I only have about 2 a year) so I'm trying to figure out my body.
