BBT

So here's what i know about Basal Body Temperature.

First of all, you need a BBT thermometer, which takes temps with 2 decimal points. So you get a much more accurate reading. You need some form of app... I use Kindara (which is free) and Fertility Friend (which is about £27 a year) 

Kindara has a great community, but FF is much better for analysis, and it will tell you when you've ovulated and stuff. 

So every morning as soon as you wake, without getting up or going to the loo, or talking or anything you take your temperature. You can go it orally, or vaginally. And record it. General concept is before ovulation they are low, and after ovulation they are high. 

So my temps before O are below 36.30 and after O after above 36.30. 

The rule of thumb is once you've had a temp shift where 3 temps are above the last 6, then you've ovulated. And your day of ovulation is the last day before the temp shift. 

The most misunderstood thing about temping, is that BBT doesn't predict ovulation, it confirms it. 

The prediction comes from the opks, and cervical mucus.
