I’ve been using clearblue to track my ovulation...last month(my first month ttc) i tested on a sunday morning and got a positive surge, tested again monday morning and got a negative surge..no big deal makes sense 24 hr period i ovulated somewhere in between...this month i again am tracking took a test this morning around 5am got a positive result just tested again at 9:51pm and got a negative result...either im the fastest ovulator known to man or i need a different kind of test...i thought it was suppose to detect two highest days? How within 17 hrs did i go from a positive to a negative? And have followed basically the same pattern two months in a row? Anyone else been known to ovulate that quickly? Sure makes me glad we’ve been baby dancing this week!!
