Any help appreciated - tmi

This is a little bit long and slightly confusing so thank you for taking the time to read.

I have had irregular cycles since coming off depo last year and started taking Vitex end of may as heard can help. Well every 11-18 days my cycle restarts and I go through it all again.

On the 15th July I got my solid smiley on clear blue advanced - between 13 to 16 I had a light bleed (so I have naturally assumed it was af)

24th July I got another solid smiley (took just out of curiosity) and today flashing smiley

I have also notice the below and was wondering if I did ovulate around 15th and this is implantation or could this in fact be ovulation bleeding?

Any advice is much appreciated
