Ovulation on CD10 with an average of 32 day cycle?

We've been trying for over a year now, with 2 miscarriages and just this cycle I decided to try ovulation tests. Based on the tests I bought it says I should start testing on CD16 with a 32 day cycle, but being who I am I decided I would start earlier. Well I tested on CD 9 and CD 10 where the line on 9 was dark, just not as dark as the control line. On CD 10 it was as dark as the control line.

Now I'm confused because based on everything else I've read and researched I shouldn't even be showing any lines until around CD16 or beyond. Is it possible to ovulate only a few days after my period ends?
