Currently on cd 60 after being on birth control for 10+ years. Was losing all hope for figuring out what my body was doing and recently made the random decision to start opk's. and last night it happened... a very distinct positive! i didn't actually wave the strip i'd just peed on in front of my husband, but i got the job done, bd-ed immediately and will hopefully bd today too  o cover our bases. wish us luck!
