2 peaks in one month!? So confused 😠

So I started clearblue advanced opk and got flashing smiley on CD 9 up until CD 13 when I got my peak. Well I am either 8 or 9 dpo and yesterday I wiped and got an abundance of EWCM which I never get in a cycle ever. I was so confused so my husband said just take an ovulation test. So I did and got another PEAK ON CD 21. I’m supposed to start my period in 6 days now and I am so scared that my body isn’t acting right. I took a pregnancy test this morning and got BFN. Can someone please help I’m convinced because of google I have infertility and am freaking out. Please help 😪
