Weird question but okay
It could be a yeast infection starting, it could be
your ovulation days starting, your vaginal discharge will increase prior
to ovulation.
If your period was unusual, you are not on birth control and had
unprotected sex, did you take a pregnancy test? If not, maybe that's the
first thing you might want to do. If negative, it should be fairly
accurate since your period has been and gone. If positive, then your period was actually implantation bleeding and not your period
