Ok, so I do have the time to track BBT, OPK, CM etc etc but I don't want to overwhelm and stress myself out. This is my first month TTC. Does anyone suggest one particular thing to focus on over the others? If nothing happens after a few months, I wouldn't hesitate to pay more attention to any/all methods, but as of right now I just need one thing. What do you think?

Tracking CM and OPKs isn't exactly hard, but I don't blame you if you don't want to start with all 3 things. FWIW, my first month I think I just tracked temps at first, and then CM just occasionally. By my second month (when I hadn't detected ovulation the month before) I started tracking all 3 consistently.
I was worried I would spend too much time thinking about TTGP, I mean I already spend a lot of time thinking about it, right? When I did dedide to fully chart it was actually a huge relief and I now feel much more in control of this process.
Good luck to you!

Fertility Friend has a lot of great tutorials about all the fertile signs and charting if you want to peek at them. I particularly like their tutorials about cycles because school sex ed and bio class really dropped the ball on giving us a real idea of what cycles are like in the real world.

Also, don't feel like it's all or nothing. You can try BBT now and then add OPKs later. Or just start with OPKs and see if you are good about having sex during your fertile time etc. You can always adjust what works best! Good luck!
