Ovulation, implantation timeline

Leah

Has anyone had implantation sooner than expected? When I ovulate I get pinching pain. Then a few days later I had sticky discharge with slight spotting that lasted two days. I also have cramping. But I just finished my period on the 29th and not expected to ovulate until tomorrow and peaking around the 18th. Lately my cycles have been long after I had and iud removed.

Just wondering if it’s a possibility for being pregnant or just my uterus being angry at me
