Yes, I posted a thread about it a couple days ago. Well, it wasn't so much from BD but from my climax. Hugest cramps ever right after; I could barely move or stay standing. I was 11dpo so I was scared that my uterus was contracting too much and causing a mc if I were in fact preggers. My temp is still high, so nothing bad's happened yet.
I looked up info and everything said that BD at that time is perfectly safe, you wouldn't lessen your chance of implantation (at your dpo) or cause a miscarriage (at my dpo).
