I Have a Question

If doctor says nothing wrong with you or can't find nothing wrong.but you are having strange problems like with your monthlys having really heavy periods then they just stopped and haven't had no periods just few spots every now and then your not on any protection no pill nothing haven't had a period for about 9 months is that normal.or that you are having problems with your bowels controlling them.and every now and then you are getting aches and pains and just don't feel well some days and feel tired but you told doctor but insists nothing is wrong.i feel like I am a weak moaning person but sometimes I just can't help but feel ill but I can't help it.
