stressful cycle¿?

my period has always been irregular my whole life but once I was on birth control for a while (still am on it) my period always came every month and may not have always been on the exact same day but was always in the same vicinity of the month. but this month my period is 12 days late. I’m not too worried because I’m a virgin but it still worries me because that’s my body not doing something it should be. I was just between jobs before I started my new one today and my Apple Watch got stolen at my old job and I just got in a car accident yesterday, so I feel like it could be stress but idk. any suggestions on how I can get my period back in check? please and thank you xo
