Hi....I used clearblue OPK...I had been using cheapie ones but thought I would try CB..My cycle is 35 days some months and 28 some others well the opk gave me a smilie face on day 28....the last 4 months I have been getting day 21 blood tests done & they all came back that I was not ovulating....ob becoz my cycle was 35 day instead of 28 those months...I will say that when my cycle was longer I would have (what I now know to be ovulation pains) I always thought my AF was on its way & I wouldnt feel like BD but last month although it was a bit painful I just bit my tongue & did it anyway!! Sorry I am rambling....good luck & have them pillows ready!!
