Charting is really good to work out what the heck your body is doing, and then after you have the hang of that, using some other method to check ovulation timing...ie poas or your microscope. I would wait til you have charts sorted before using poas or microscope tho as that can get a bit obsessive (and expensive if you use poas!).
And the biggest thing as someone mentioned is to not test for BFP until you are late as it can just be heartbreaking to do every month. And don't read into signs...half the time the things you think are 'symptoms' are just stuff that has happened your whole life you just didn't notice before now!
And last of all...don't listen to people saying just relax and it will happen....if you feel the need to find out as much info as you can then do it!
Good luck
