I feel like I see the faintest line EVER 😭 Only 9DPO but AF due today!

This was with FMU. I got a positive ovulation test on July 15th, but AF is due today so idk when I should test. My last period was June 19th. I usually ovulate the 1st but it was 2 weeks late this cycle. Ive had horribly sore nipples, and have been sooo irritable this week. I’m just in limbo!
