I think ya might be right hun! Definitely get yourself a BBT, and CD1 is the best day to start, you may see it start fairly high as my temp goes right up on the first day of my AF..
Just make sure you temp at the same time everyday, dont do anything before you have taken your temp,so open your eyes reach for your BBT and take ya temp, luckily the BBT's store your previous temp so you can always fall back to sleep if need be, for example I temp at 6:30am as thats the time I have to get up during the week, it kills me to do it at the weekend as well but you have to keep it consistant...
Will you be using FF??
