Almost positive OPK

Courtney • 28 years old. Happily Married to a woman. One 11 yr. old boy. Ttc Baby #2 since July '14. 4 losses. Diagnosed with "unexplained secondary infertility". Ready as ever. First egg retrieval January 15 2022. 12 embryos frozen. FET in March! Update : FINALLY P

Yesterday I had an almost positive opk. I mean sooo close. But I tested 3 hrs later, and it was faint. Tested again today, and light lines..... I know I haven't ovulated or even come close. No cm no aches or changes as I usually do approaching ovulation. I guess my question is, has anyone gotten an almost positive then obviously negative then certain positive later on? Thanks for your input!

A little Back story: This is our first month using a fresh shipping donor so I need to time this perfectly. 😞
