Does it look like my period will start soon from this 0.2°F drop?

Using FAM for birth control but afraid I messed up by having unprotected sex 4 days before ovulation. Hoping that this drop means af will be here soon, but I've never had a luteal phase where my bbt steadily rose like this. I guess I can find out in 2 days anyway if af shows up, just curious what others think!
