please help i’m really concerned

i’m on birth control and use condoms when finishing so don’t think i’m pregnant, my period came on time too after my bc cycle (patches).

but my period also got messed up bc of a mishap with my birthcontrol and the pharmacy (was using condoms completely safe during sex) so it is later then my period should be bc of the birthcontrol.

i’m just really concerned bc i’ve never seen this before in my period. I usually have awful periods and this once’s been not too bad. but is this normal? it just looks so weird and i don’t know what it is. it just felt like a normal clot but looks like skin?? i’m freaking out, please be kind. it’s probably an inch long.
