'm 15 years old and I have never been consistent with my period, I am a virgin and I legit have nothing to do with boys. I've missed my period for 4 months now and I'm starting to get worried. I have missed it for three months before and it eventually came but the last period I had was a bloody discharge and only lasted for 3 days. I'm hoping it's nothing serious but I don't feel I can talk to my mum or anyone about it.
