WTH? Near pos OPK after O?


Hey guys. On Sept 17th I got my first positive OPK and that lasted until the 19th. Late 19th and all of 20th was a strong negative. I went to the ER yesterday and was diagnosed with a corpus luteum cyst and today I got this with my OPK. Can corpus luteum cysts cause false positive OPKs? Or is it not a corpus luteum at all and I had a failed ovulation? Thanks guys.
