Peak fertility my first month, only high last 2 months, no peak.

We're glad you're using our Fertility Monitor, Michelle.  There may be a small percentage of cycles in which you don't see Peak Fertility.  This can happen if a test was inadvertently missed, if you're having an unusually long or short cycle, or if you didn't ovulate.  The monitor can be reprogrammed by following the instructions on page 28 of the instruction manual, but reprogramming your monitor erases all the previous information stored about your cycle and isn't reversible.  Rather than reprogramming it, please call us so we can learn more and talk through your questions.  Our toll-free number is 1-800-321-3279 and when calling, please mention reference #FB501.  We're here to help Monday through Friday from 8:30am-5:00pm Eastern time.
