Thanks for your help and advice, Kathi49 and Jo55.
I understand the fact it is natural but it shouldn't interfere with people's lives if it's natural? Just a thought.
I also understand the fact and agree with you on the fact that I am young and not to make myself infertile as I may want children of my own. I haven't got a boyfriend yet, that's probably a long way off.
Work and career is what'll probably come first as I can't see me getting a boyfriend anytime soon.
Would work sack me if I kept having a 5 days to a week off every three weeks? Would they understand about this and keep me? I don't know. That is what I'm worried about.
I have thought about going to my GP but they'll probably just tell me 'it's natural'. I could try and see a gyn.
Thanks once again, Kathi49 and Jo55 for your help and advice.
