Don't judge me please

I already feel stupid lol..
I'm just barely 20 years old and decided to look at the TTC Topic and I'm suddenly realizing how clueless I am with stuff like how to detect ovulation and the days that are best to try to conceive, implantation, and checking your cervix etc and I just feel clueless and stupid.. 
We aren't trying for a baby yet but is all of this completely necessary to know when we want to try and is there an easier way to teach myself about all this stuff?
