BBT increase without ovulation?

Hi
So I've been coming off the depo injection since January and my cycles still seems pretty messed up. I got my periods back in late March, and had about three periods over 6 weeks. I then had a proper 28 day gap between April and May, so thought it was sorted. However, in mid-May I had either another mini period or an ovulation bleed - I have no idea which. I had ovulation symptoms like raised BBT and egg white CM, but no positive on the OPK.
Anyway, I've only been tracking my BBT for about a month. It's been raised to about 36.7 C since I started in May, including over the "ovulation bleed/light period". However when I got my proper period a few days ago, it dropped properly to 36.1 C.
Essentially, while I think my cycles are still out of sync, it seems my BBT is acting as expected. Obviously I need to track longer for more days, but does this suggest that I am actually ovulating???
Or can my BBT still act like this without the actual ovulation bit?
As an aside, I think my oestrogen is still high and my progesterone low as I'm getting weird symptoms like egg white CM during first few days of period, hot flushes, very tired etc. Could this be the cause of my BBT behaviour rather than actual ovulation?
