I’m on cycle day 36 and 4 days late on my period? I was supposed to get my period on the 16th. Basically tomorrow would’ve been the last day of bleeding if I had gotten it on time. I tried not to worry and said ok it’ll just come the next day, it didn’t, so I tried to relax and waited but it didn’t again and still hasn’t! I’ve been regular and it anything a day or two early or late but never 4 days going into 5. (Btw I’ve never had sex)
