Pro's and con's of being informed about TTC

Sometimes I wonder whether knowing a lot about TTC is a good or bad thing. I used to think you had to have sex once or twice and you've get pregnant, obviously when I was about 16/17, but now 3 years on, I've learnt so much since last year and it's crazy. About OPK's, ovulation, the TWW, the ovulation window, sperm stamina, BBT's, CM, all of it! I think being a little bit informed is good but sometimes too much information drives us all crazy about TTC as it's so hard to not think too deeply into it as we all want it so bad!! I think I just wish they taught a bit more about it at school!
