Missed period negative test 😞

So my period was due today... it’s always on time without fail... But she was a no show today... I took a test & it was negative should I just count this month as a bust or should I test again? If so when? Thank you

I had sex 3 days before ovulation & day before plus day after

I didn’t test with FMU I tested on a 4 hour hold as I forgot to test when I got up 🤦‍♀️
