very concerning

hi guys. so todays the day i’m supposed to get my period - i’m on the pill and always get it in the morning or the night before- but it has yet to show up. i did just move back to college and start class this week so i’m thinking it’s stress? i took 2 tests (rapid pink line and digital ER) today and they both were negative.

i took the pill within a 2 hour range the whole month, never missed a pill. had sex prob about 7 times for the month with pull out every time.

what do u guys think?
