Spotting after sex 😬

CP’s mom

I’m 4+3 today. Over the weekend the bf and I had sex. Later I went to the bathroom and there was dark red blood. It was only there when I wiped- nothing on liner that I wore all night. Sat and Sun it was just some occasional brown-rust colored spotting. Today nothing. Called dr and I go in for beta testing tomorrow. Anyone experience this? I’m nervous since i just had mc in October. 🙏🏽🙏🏽🙏🏽🙏🏽
