If it's someone you haven't had carnal knowledge of. Then you should check how long she had had s**x..

Maybe her thing gets tight

It’s normal to have vagina bleeding during/after sex especially if she's in her menstrual period, and there’s probably no cause for concern. Bleeding after intercourse is also normal if it has been awhile since your partner's last sexual experience. 

However, if this is not the case, then it could be caused by trauma/irritation to the cervix(if there's not enough vagina moisture, or if the penetration was too vigorous this time).
There is also the possibility of other root causes. Like; it could be a symptom of an infection, or an early warning sign of cervical cancer.

She should see a doctor if this happens many times after sex or if the bleeding is associated with pain.

I hope this helps.
