TTC - any tips?

As the subject line says :) but here's a little more info lol

I had the Nexplanon implant for a year and a half.. Hated it.. Got it removed May 3, 2017. We're not expecting to conceive right away, but I'm curious about any tips? We have an almost two year old (will be two in August). I don't want to get all into it and start taking my temp and using OPK's though :/ we did that for the longest when trying to conceive our son (it happened when we gave up) and it drained us..

So what does everyone think? I've tried tracking my cycle with numerous apps but being I just got the implant out last month my cycle is a little crazy.

Thank you in advance!! :)
