a friend of mine (I'm not disguising this as myself, it really is a friend who has this problem) who is 20 hasn't had a period for 4 months. She is definitely not pregnant though. lately, she has been getting period type pain. in the past week she has also had 2 nose bleeds which she has never had before in her entire life and was up all night one night this week throwing up. she thinks that could be down to a bug or something she ate. she's making another appointment with the doctor because she started getting the pain. when he found she had missed 4 months worth of periods, he did a quick internal examination and couldnt find anything wrong and said she should go and have a scan. the date for the scan hasnt come through yet - she could be waiting 6 weeks. does anyone have any ideas what this could all be down to as she's really worried. Thanks everyone. xoxoxox
