Your cervix is extra sensitive in pregnancy, so it could be irritation from having sex. Keep an eye on it. If it keeps up, worsens, or you get painful cramping, get it checked out. Happy thoughts your way!
Totally normal to spot a little after sex. It should turn brown quickly, but if it turns bright red and/or increases get checked out. Or if cramping as PP said.
