Quite different OPK results only 3 hours apart. Help

[bbymc]

I took the first one at 8am (with FMU) and the second about 11am. As you can see the second one is darker but I don't think it's positive. Does that mean I'm likely to be ovulating in the next 12 hours or so? I thought it was more of a gradual progression over a few days to get to the right time? I don't have any other symptoms of ovulation that I'm aware of.

I'm CD 13 of a (usually) 29 day cycle.

Can anyone help?

Thanks xx

Don't use fmu unless directions say. It gives false results
