This is my first month using the monitor. Had few lows starting from day 6-day 21 then on day 22&23 I had peaks and then a low today which is day 24 ..the weird thing is that I only have a 25-26 days cycle throughout my adulthood , so does this means I have a very short luteal phase and conception is not possible? BTW I have 2 boys aged 10 &3 and i'm 35 years old and my period is regular and always on the day ..advice pls? thanks
