Finally TTC! My daughter is 9yrs old!

I've been on the BC pill for a few years. I finally decided to stop and work on making a baby just a few days ago. After stopping my BC I began spotting, maybe a little more than spotting. I am wearing a tampon. Its been 2days of bleeding. I know you are supposed to finish the BC pack but I didn't. I started 3days of week 1 and stopped. Long story, but I finally felt ready so I had to stop! :) how can I get back on track with my periods and know when I'm ovulating and fertile? I'm still trying to figure all this out. Is it possible for me to get pregnant soon? I need some insight plz.. Thanks ladies!!
