Ttc right after last Depo shot

Ja

Hi all! First post here :) My fiance and I can't wait to start our family. I've been on the Depo shot for about a year and a half/two years. I just had my last shot 2 weeks ago. I did still have periods and spotting while on it(though irregular). My question is- Do I need to wait until the 13 week mark to start really trying to get pregnant(Taking bbt and Ovulation Kits) or can we start trying to get pregnant now?
