Month 3 TTC. I have been using clue blue digital ovulation sticks since month one but I noticed something odd this am. 

So month one I got 5 fertile days (blinking smiley) no peak (solid smiley) but just off BC so it's understandable. Month 2  one fertile one peak. Hmmm ok losing days but I'll take it. Then this month no fertile and 1 peak which made me nervous. The box says don't keep testing after peak but I wanted to try this month so peak last 2 days on the stick so once the stick cleared I tried again yesterday...low fertility (Empty circle) ok makes sense if I had my peak already but then just now tried it again and I got a high fertility blinking face. How is it that I got my peak then low fertility and now back to high???
