Third day getting positive OPK CD27

Took a clear blue test two days ago and got a very faint positive. But took a frer yesterday with fmu and it was negative 😞Ive been taking ovulation tests everyday for the heck of it and it's been positive the last three days and I'm supposedly almost to the end of my cycle. Usually my cycles are 31-34 days. Also, my usual aunt flow symptoms aren't existent this month. I usually have super sore boobs the second two weeks of my cycle but not this time! What is going on!!
