Bleeding after sex following D&C

Sam • 🇬🇧 UK Full Time Mum, 2YO girl, pregnant with 2nd
I had my D&C last Thursday evening, I only bled that day then it stopped the next day. So we had sex Tuesday morning, (I know it's soon but we hadn't had sex for nearly 3 weeks before that because I was bleeding every day before my D&C) since then I've been bleeding again 🙈 Could we have caused any damage??
