Hi Catrionalee
It does not mean that something is wrong with you. Although it is unusual some people do have a lower temp than the average. If our temp is below 36 then just enter 36, It will not make much difference providing that your temp goes up to above 36.5 later in your cycle. Give the program a try for a month or so and then if you are not happy with it email me and I will modify it for you,
