Hi shoegal, not long to wait now! I would say though, if you get your AF regularly, you most likely ovulate. For some women the OPKs just don't work, but they still ovulate. The digital ones might be easier for you, but if they don't work either and you're worried try temping.
It is quiet on here! How are you, golden?
I'm on cd15 now and am waiting for ovulation. I have 4 sticks left of the advanced cleabrlue OPKs, and got a flashing smiley this morning. However, I have noticed myself that ov is coming closer, so I have decided to save some money and not buy anymore OPKs. The signs are pretty clear, by monitoring cm and cervical position, and I get pains on the day before ov, and I temp as well, so I can't miss it can I! 
I'm relieved though that so far ov seems quite on time, unlike my last cycle where it took three months! Stupid bc pill.
