This is Dr. David
it sounds like you could be developing some vaginal atrophy after your hysterectomy and removal of your ovaries.
your hormone replacement therapy estrogen dose might not be enough for you.
you need to see your GP doctor or get a gyn examination.
you might benefit from a vaginal estrogen cream like premarin to help with vaginal atrophy
you need to be checked for vaginal prolapse as well with an exam
talk with your gyn doctor in april about if you have vaginal atrophy and if you would benefit from a vaginal estrogen cream. I think it will help
let me know if you have more questions.
