i'm 37and is diagnosed with hyperthyroidism since 4 years back,but for over ten years i've been experiencing bleeding during sexual intercourse.i've gone thru 2 serious relationships,during the last one  i had heavy bleeding non-painful cuz i'm not into large penis men. the bleeding occurs mostly when i'm having an orgasm.it stops after but i would spot throughout the day ,then it goes away.i went to numerous gyno's and medical doctors and they seems to can't explain the reason.i've done a cancer smear no problem.i have a 19 yrs old son and lost a pregnancy in 2011 and is desperately trying to have another with my new fiance since, no chance. still have bleeding ,but not that often or heavy.frustration is mounting between me and my partner, leaves me wondering could graves disease/ thyroidism be the cause of my problem?i need some help as to what to do.
