My birth control Situation

Zipporah
I had my son December 17,2015. In January 2016 I started the pill and then in February I switched to the depo shot. In October I switched back to the pill. On Monday this week my husband finally agreed with me that we should have another baby! I stopped taking my birth control on Tuesday. I know it's different for everyone but how soon do the hormones take to get out of your system? I feel like in a perfect world I should be able to get pregnant rather quickly since the pill is ineffective if not taken properly. Has anyone else had experience with this?
