Clear mucus,followed by thivk white discharge/no ordor/no ir

I had unprotected sex with my partner that gets tested regularly probably a week before I came on my period. I wear pads instead of tampons during my menstrual but they can be rather unconfortable. After my period I noticed a thin mucus that would occasional drip from my vagina, then I noticed it got more excessive and thicker and white but more like a lotion not clumpy. It does not irritate me and there is no ordor to it but it is a lot of it to the point it is uncomfortable, makes me excessively wet, and pushes out as if I was on my period sometimes . I am trying to figure out what this may be. I have had BV before and seem to always have problems with my discharge more so after my periods, so I dont know if it is this again but I do not think it is a STD, any suggestions to what it is and how to make it stop?
