Like the title says, my period is a few days late. I’ve been having bad cramps in the morning and through out the day, since the day that my period was supposed to start. The cramps usually happens towards the end of my period, but since I’m not on it yet, and it’s late, I’m concerned. Should I be???

Also, my periods have been come later than expected. I’ve put it down to stress, since I had exams, but it ended a month ago and I’ve been on holiday since.
