is this normal?? help

ok so like a month and a half ago i took a plan b pill. my period came last night and it was 2 weeks late, and it’s like thicker and brownish and a weird texture. idk if this is normal or not, but here’s a picture. should i be worried? could i be pregnant at all or is that not possible

it’s also like stretchy? i don’t know how to explain it but i don’t think that’s normally how my period blood is
