A bit of both, depends on the time of the month and what are the circumstances? Are you pregnant? Do you have an infection? It is much thicker like mucous when pregnant during the end. It is more liquidy throughout your month. before and during ovulation. But any discharge with a funky color or smell is bad. Could be signs of infection and you should see a doctor.
It can be both, depending on where in your cycle you are. Generally during puberty it is especially annoying and thick, and then just before girls get their periods, they get thicker discharge.
If it bothers you you can get panty liners and feminine wipes to make you feel a bit more fresh down there.
Both depending on what time of the month it is.
