Bleeding right after ovulation

Rebecca

A friend of mines is curious on why she is bleeding and having pressure after she pees. She just ovulated and had sex during her fertile window she doesn't have any STI's she was just tested last week. I told her she might have a bad UTI but she wanted me to ask some of you ladies she doesn't see her gyn until next week so idk to tell her. What do you ladies think this could be.
