rina:Second qs was that Is that the BBT charting is better than that microscope.If yes .Than how do u make a chart??And if u put ur BBT data every morng by taking TEmp every morng how do u come to know when u are ovulating Cos is says that the temp rises after O ..So how would u know u are abt to O. Or it is like this that u chart for initially 5-5 mths to know the tiem of ovulation and than plan ?? I mean how does that chart work??
BBT charting should be accompanied with OPK/Monitor. The difference is OPK/Monitor tell you when will you ovulate while chart tells you when did you ovulate. Chart even tells you about your LP or if you are pregnant by showing high temps after 12DPO. Join FF, buy Basal Boday Thermometer and record first day of AF. You can start anytime by adding temp. You can add other data like cm, cervix pattern, OPK details, BD, medicines you are taking, symptoms etc.
To get better idea you have to chart for 3 cycles. If you have regulat in periods then you will get idea in one month.
