Don't really have a good advice, I have been getting Peak reading every month, but no viable pregnancy yet... The only suggestion I have is to call Clear Blue at the number on the manual, at least they might be able to help you rule out some of the possibilities... Good luck!
Thank you! I will call this weekend. I am now on my 15th day of getting "high" reading. So frustrating but keeping my fingers crossed!
I also just had 2 weeks of "high" fertility but didn't get the "peak". I also took Clomid 100mg (50mg x 2 daily) so I don't know if this affected the readings or not.
I have not been on clomid myself but my sister was and it did interfere with her readings on the monitor.
I finally got a "low" reading today - after 16 days of "high" readings. I am hoping I am pg but won't know for another 5 - 10 days. Will keep you in my thoughts as well - wishing you luck!
