I used the advanced clear blue opk and it went low to peak, had no highs. I then re tested after 48 hours, expecting it to show low, but its showed peak again. Does this mean i havent ovulated? Or clear blue faulty and it should have shown the first peak as a high, now im peaking. Dont know what to think.
Just to add i used cheap ones, when clear blue first showed peak, they showed positive.
