I've only just started tracking with ovulation test strips in my previous cycle - seen in this image:

I know according to the tests my LH peaked cycle day 12 and was predicted to ovulate cycle day 13.

Now I am in a new cycle. My period lasted a couple days longer. I started testing at cycle day 8. LH levels began to rise cycle day 11 again but did not peak but rather dropped and started fluctuating quite a bit but I never got a positive reading (still testing twice a day). This can be seen in these images:

I am guessing that because my period comes anywhere from 23 days to 32 days in a cycle, that my ovulation will vary within that range of difference as well but it seems like I'm not going to get a positive test from this cycle?? I'm confused, what is happening?
