Depo shot and ttc

Hi all! Long story short after a period of bad experiences and feeling like I didn’t want to have anymore children (I have one daughter aged 2) I went and got the depo injection. I’ve only had the one and it “runs out” today. I was wondering how long it has taken you to conceive since coming of the shot as I’ve realised this was a stupid, knee jerk reaction to something bad and do want another child. Thank you!
