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!
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.
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!
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!
