Skin colored gloop after plan b?

hey everyone! i had unprotected sex on feb 3, and took a plan b the next morning. my period was a day late, which is normal for me, and came on the 11th. i was past ovulation when it happened, and i’m on the mini pill. however, i recently found out that plan b doesn’t work if you are over 175 ish lbs. i am 216. when i did get my period, there was a weird fleshy glob of something. it was squishy but not mucousy. i don’t normally get clots on my period so i’m not sure what it was. i am a little worried since today i ended up being a bit nauseous this morning, but that could be from some vitamins i took. i don’t normally take vitamins either, but i broke my foot last week and my leg has been cramping badly in the cast. i took vitamin c, zink, and calcium i believe. when i had unprotected sex, it was both my bf’s and i’s first time. we’ve decided to wait to do it again just from all the anxiety i have had from the whole thing. but does anyone know what the fleshy gloop could have been?
