Hi,
I am TTC for past few months. I record my BBT every morning. The fact that my BBT was down twice makes me upset. One month it was down on day 11 and 12 and then it rose up. That was not concern. But this time, BBT was down on 11th day (35.9 degree centigrade) and then on 13th(35.7 degree centigrade). 35.7 was the way too low temperature recorded so far. My ovulation test strip kind of showed two dark lines on 12th day. On 13th day it shows lighter line. So I am confused. If I already ovulated around day 12th, why should my BBT go down on 13th? Pls help if any one has same symptoms or more knowledge about this matter. Thanks
