ovulating on cycle day 13? UPDATE!

Hi ladies! So my cycle is 32-33 days. I've been taking the clear blue advanced ovulation test in the mornings and just the regular one at with just a smiley face at night. Yesterday and this morning on the advanced I got the flashing smiley (high fertility) and last night a negative on the regular opk. Well tonight I got the smiley. I'm only on cd 12. Is that possible or are the tests wrong?  
Update: I took the clear blue advanced it's now a solid smiley(peak fertility)! I just feel like it's so early!
