Hi
I have been testing a few days with the cheap opk's off ebay and have not got a postive but last night shortly after midnight I had what I thought was a positve with both lines more or less looking the same in depth of colour.
However I am also testing with the clearblue monitor and tested with that at 8.00am this morning and it only gave me a high reading.
I feel so confused is it possible that the lh surge came and went in between midnight and 8.00am this morning so that the monitor missed it.
