Red dots on toilet paper after sex

Sarah • Baby GIRL due July, 2019 🎀

I had sex with my husband and I went to the bathroom to pee and clean up.

It looked like someone put 3-4 red dots (size of the end of a needle) on toilet paper . It wasn’t on there after the third wipe. There’s nothing going on now .

I know some times spotting happens when you have sex but it hasn’t happened to me yet at I’m 25 weeks .

So my questions are: is it being red a concern? Should I stop having sex till I discuss it with my OBGYN?
