Hello Doctor, Please explain us how to track the ovulation using Basal Temp Thermometer. Many sites say different procedures. Please help me so that we won't miss the important days. I have regular cycle of avg 27- 28 days.

Yes many sites say different things - agree, but stick to old methods of measuring morning temperature before brushing teeth or taking tea, means just after waking up. If temp has been 97 for first 12 days after cycle, on day 13 there will be a dip by a point and on day 14 there will be a rise by 2 points or more and it will remain so till cycle starts. Day 14, when there is rise in temp. By a point is ovulation day and life of ovum in urerus is 48 hours. You are lucky to have a regular cycle and I am sure you will find the old time tested method useful, though there are ovulation kits available in market too and they too can be wrong due to human error.
