I am on the Clearblue CBFM trial, this means that they have sent me a CBFM and all the sticks to use for 3 cycles.
However I was already using the CBFM, so now I have two.
Each morning I have been using their one first and then putting the stick into my one.
This morning I was sure I was going to get a peak. All the other signs seemed to point to it and the CBFM stick had two clear lines. On the CBFM from Clearblue I had a peak, but on my one I just had a high.
I don't know why there was a difference. The Clearblue provided one was done first, and therefore about 5 minutes before the other, and my one was in the dark whereas the Clearblue one was in the light.
What ever the reason though, I just thought I would share it. So is you don't get a peak, it doesn't mean you're not ovulating. Also, when you have a high, keep at it!
