TMI is this a miscarriage ?? Or something else .

Can this be a misscariage or sign of early pregnancy? So I had unprotected sex on may 14 but took a plan b on may 17. I also had unprotected sex June 7th. The image is what came out of me today and I just had milf cramping after and no bleeding. I also had severe cramps on June 9th but no period .my next period is due in 8 days .i also took an early pregnancy test and it came back negative . Can this still be a miscarriage?
