Late period but negative pregnancy test


Waited three days and still says negative. Could there be something wrong with me if I’m truly not pregnant? This is a total mind game!

I’m 5 days late on my period and I’ve taken two tests, both negative. I’ve been feeling crappy but not really pregnancy symptoms, more like body aches/ headache etc. Been trying since August. Any advice? Tips? I thought if my period was late I’d for sure have a positive test. Please ease my mind!
