So I just started using OPK's this month. I have a 35 day cycle. I took quite a few and kept getting low fertility and I was starting to think I was broken. Low and behold yesterday I got my first flashing smiley on cd 21! Today I got another (I bought the clearblue advanced digital). The only downside? Hubby is away in California on business and comes home Friday. If I get peak on Friday do you think we have a chance this month?
