Need advice opks sorry it's abit long lol!

So I had my coil removed on the 19th of June 3 days after my light monthly period I still got when I had my coil in.

Then on the 21st of June I had a heavy bleed for 4 days...

(would that of been my period or not?)

I then tested with a opk every day until the 4th of July where I again started bleeding heavily for 5 days. A really short cycle of 13days???

All opks were negative. I really have no idea where I am in my cycle or how long it is?

I've been testing (opks) every day since the 9th of July still negative. It seems i haven't ovulated at all since having my coil removed??

Can anyone help with some advice please ?
