Hey Ladies, just wanted to let anyone know who hasn't tried the newest CB Advanced OPK that it is great! I took clomid cd 3-7 and had been testing for several days with no symptoms, the first EWCM I had was on cd 19 (sun night) so I tested with this new test and it was positive with flashing smiley face..meaning my estrogen levels were high, and my LH would soon be at it's peak too. I tested yesterday and today too and now have my solid smiley meaning i've reached my peak. This test gives you best 4 days to conceived, rather than 2. I was able to get a head start on the bd'ing by using those tests. Fingers crossed this is our month!
