Random bleeding after sex

So my period isn’t supposed to start till the end of the month, apps are predicting about the 29th (5 days). I got my tubes removed so I’m not pregnant.

Wednesday night my husband and I had sex. He fingered pretty roughly which is why I thought I had bleeding then. Yesterday I had nothing. Then all the sudden today, I felt stuff and thought it was just discharge. I went to the bathroom and saw it was fresh blood. I’m not cramping like I usually do when starting my period.

Can this be normal?? Doesn’t really ever happen to me. I guess I could be starting a bit early which would put me at cycle day 26. I’m usually about 28 day cycle but a few times had a 30-32 day cycle.
