Curiosity

I had my period on the 11-13 it’s a normal 3 days for me. I had intercourse on the 19th and a few hours later I had gone to the bathroom and noticed that there was what looked like a stripe of blood with clear discharge. And it only happened one and then on today the 21st I had the same thing happen but this time it’s more pink. Now when I first saw it there was more then I had to just make sure and at that time I took a picture. If you all don’t mind helping another women out that would be great!
