Hi I am 60 years old, and yesterday noticed some light spotting from the vagina, it is a light brownish pink, not a lot and watery. I am a breast cancer survivor of 5 years, I was on arimidex till last August, which was the 5 year mark. I have not been sexually active since I was diagnosed. I am obviously concerned, I will be contacting my OBGYN first thing tomorrow, but would like an opinion. there is no pain, just the light spotting. I am also on thyroid meds for inactive thyroid.
