Bleeding after sex at 13 weeks

Jennyfer • currently pregnant with baby #2. Mother to my 3 year old.

We got frisky and had really good rough sex, I had one orgasm at the beginning and 2nd one close to the end. When we were cleaning up we notice some light red blood, I’m cramping a little and I noticed 2 tiny dots of grayish tissue. Idk what to think? This never happened with my first pregnancy.
