I had breast cancer in Oct 2009 - lump removed and 4 lymph nodes removed, had 6 lots of chemo, 25 lots of radiotherapy, 18 lots of herceptin and 10 years of tamoxifen - which finished in 2020.  I am now 53 and since taking tamoxifen, my periods stopped and I probably had about 4 in the last 10 years.  I contracted covid 2 weeks ago and had a week off sick from work and then I started a period which I thought was weird as I don't normally have them.  I am now on day 10 of my period and it doesn't seem to be stopping.  It's not that heavy but it's still there and I am quite concerned now as this isn't normal and I don't know whether to phone a doctor on Monday as it's now Saturday.  I have researched about periods and covid and it seems there are quite a few women who have had longer periods but I don't know if they have gone through breast cancer!  Has anyone got any advise?
