First Month TTC!

Hey Guys,
I am new to this forum but wanted to ask how soon after coming off the pill did your cycle regulate? 
I finished my last pill packet on 6th January, AF came like normal on 9th January. I have no idea when I'm ovulating so have been checking my CM. I think I'm now 11 DPO roughly but not sure! So annoying when you are TTC and you don't know what to expect or if you should take a pregnancy test 😬
