Positive Opk 6 DPO

I have gotten a positive OPK last Sunday 8-19 pretty sure O happened on the 20th.. for a few days I’ve had back pains and cramping (not any longer) since this weekend I’ve been getting EWCM so decided to take an OPK and it was positive..... ugh WHY?!

for the record I know you get a second surge.. but does that surge happen 6 days before my next period??

HELP!
