LARGE CLOTS A DAY AFTER SEX😔 7 weeks and 5 days

HELP!

Had sex yesterday and now I started bleeding. On top of that, I passed out clots. Large clots… also, not sure if i was imagining. Not sure if it was cast or flesh.

I called my ob and he said it’s pretty common after sex? But this isn’t spotting.

Any advise? 🙏🏼
