My periods are 8 days late, I went for an ultrasound and everything was fine but my endometrium was 2.15 thick, so I was told that the delay could be because of hormonal imbalances as I am on some medication, plus earlier on the month I had taken an emergency pill, I just hope everything is okay, cause I have been experiencing cramp like pains all the symptoms I have during my periods, yet I'm not seeing them, please advice
