Hello, I am a woman who is past menopause. I have not had a period for well over a year. Due to menopause, my vaginal walls are thin. I am on a hormone replacement therapy for this and other issues related to menopause. After relations with my husband I had a little spotting. Am I required to go to the mikvah since the cause of the bleeding is not from my menstrual cycle? Also, if doing a bedikah check may also cause bleeding. Please advise. Thank you.
