Help! PCOS & Faint Line!!

Hey guys! I’ve been a wreck about these pregnancy tests! So I have PCOS and we’ve been trying to conceive for a year w/ no luck. This month I finally got a positive OPK on December 11th. So figured I ovulated sometime around then? The last 3 days I’ve gotten these faint lines on the strips but all the ClearBlue tests say “Not Pregnant”. Idk what to think anymore! Looking for any suggestions! Also should note for a week my breasts have been so sore and tender, have had mild cramping, and super moody/emotional!
