Horrible cramps

So I asked some girls if it was okay to orgasm as long as theirs no penetration and said it was fine... its 11 days post D&C and I orgasmed yesterday, and 8 hours later I was having horrible cramps with red blood and clots and I'm still bleeding heavy since.. should I be concerned?

I'm also ttc after I'm done bleeding but idk when I'll stop 🤷🏻‍♀️ I've been bleeding for 11 days now
