When did I ovulate?

I was wondering if anyone could look at my dates, and take a guess at when I might have ovulated in the month below...
It was the first time using cbfm, if that makes any difference?
Sunday - first 2 bar reading on cbfm
Monday - 2 bars on cbfm
Tuesday - 2 bars on cbfm + light spotting (which I get regularly mid cycle and assumed marked ovulation)
Wednesday - 2 bars on cbfm
Thursday - peak egg
Friday - peak egg.

Would you assume that first month of using cbfm gave wholly accurate results? What about the spotting? And when, in hindsight would have been good days to dtd?
Sorry, I know there is no way of telling, I was just wondering what other ttcers thought?

CBFM will not be very accurate in the first few cycles. It needs to get to know what your cycles are like and how your hormone levels fluctuate. I tried one for 4 cycles and it failed to detect ov in 3 of the 4!

If you are having sex every other day from the end of your period, or at least 3 times a week, then you should cover all outcomes.

Thank you for answering, especially as I asked quite an unanswerable question! I will not blindly trust the cbfm reading then.
I'm not exactly sure what my mid cycle spotting actually is, but it happens on/around cd 14. Google tells me it either marks ovulation itself (the egg breaking through causes slight bleeding) - in which case ovulation happened on the Tuesday, or it's the start of lh surge - so ovulation happened maybe 24hrs later on the Wednesday. Both ways the cbfm is out a little bit.
But who knows!? Maybe I should be temping too. That and regular sex of course!
