Is this a normal ovulation cycle???

So I had my peak ovulation on cycle day 15 which was a day later than my last cycle. But I figure that’s normal. However, I for some reason decided to keep testing my ovulation and it seems to be going through another peak. Photo 1 is the lead up to ovulation CD 8-15 and photo 2 is post ovulation then the lead up to another peak CD 16-21. Today is day 21 so that test is from this morning.

Could this indicate pregnancy that hasn’t been picked up in a HCG test???
