I am currently taking monthly zolodex injections and Letrozole daily, I’ve been on zolodex 6 months and Letrozole just over a month and I’ve just started having a very light period, no pain or anything but is this normal, I had my last injection on the 8th.
I am not quite the same regime as you but I have monthly zolodex injections with Tamoxifen (since December 2017). I was having monthly periods prior to my diagnosis but haven’t seen a return of them at all. I would check with your breast cancer nurse or GP
