Positive ovulation twice this cycle

Hi guys 

I’m SO confused.

Last week, I tested positive on my clear blue test, it was the flashing circle and day 8 of my cycle (24 day cycle). I got peak fertility on day 9 and I’m assuming 10 too. I didn’t have any symptoms of ovulation during this fertile window, but we had sex 4 times. I tested day 11 and I was negative. On Saturday, day 12, I started to get left sided cramps, back pain and my sex drive was higher. These symptoms are still here day 14. Because of this, we had sex yesterday day 13. This morning, I took an ovulation test and it’s tested high - flashing symbol. I am SO confused. My fertile window on flow has now changed and I am so confused on what to do. Any advice would be great. My partner has gone away from work this week so I am really hoping that yesterdays sex and the previous days would work.
