What does this discharge mean

So my pierods are so irregular, last month I didn’t get my period till 5th of December. So I still haven’t gotten my period yet. I posted in the faint line group of a possible evap that had color. Which was probly just an evap idk anyways I had this discharge fall out 5 mins ago when I sat down I thought it was period, so o check and it was white semi stretchy discharge. I’d just like your guys personal opinions on this and what you guys think it is or why or just like I said personal opinions I’ll be including the evap and the discharge. Btw ignore my finger nails I have a bad anxiety (: thank you
