Missed period

AF is four days late. Took a test on the day Ovia said i was due and it was negative but I'm not having any symptoms of AF showing up. Anyone else in the same boat?? Had a mc in April so I'm  Kinda wishing it would just start so I can move on and not be reminded of my mc every day! I feel like my body is failing me and my hormones are just all over the place. Wish there was a restart button!
