Postpartum Blood clot. Is this normal?!?!

i just had my baby on wednesday. everything was good up until today. this is the second blood clot this size that i’ve passed today within a 3 hour period. my discharge papers say to call if passing large blood clots and i’m not sure if this counts as large. the nurses told me a size but i forgot what they said to me. i have a low fever of 99.6 and some hip/lower back pain on my left side, not sure if related
