Can you tell if you are pregnant because of temps etc...
Yes you can. If you have 18 post O high temps then you are more than likely PG, if you have 20 then you definately are.
Charting while TTC is really helpful, especially if you have been doing it for a while and you start to get to know your own body and patterns better. You end up knowing basically when you are going to O, so you can BD, and then you get to know exactly when you O'd, which is helpful for testing dates, also for due dates, it's also helpful, if you are having problems ttc, so you can see what your hormones are doing. ie can see where your problems lie in your hormones with your chart.
Plus it's fun, and you get to be more in tune with your body, and can kind of 'watch' whats going on. It's also good as a contraception too. AND of course it gives you something to completely fixate on and obsess over
