Long period and tamoxifen

Hello. This is my first post (but the site has been a great help to me). I’m 39 and I was diagnosed in Jan. Lumpectomy in feb. 20xRT in April.
My question is about periods. I started tamoxifen at the end of March, and have had a period every 5 weeks since. Up until now they’ve been very heavy for the first few days then normal. This time though, I started a week past Monday, but it was light flow and dark to start, then kind of on and off then just a light period (red) but I’ve still got it (day 10). Is this something I can just write off as tamoxifen irregularities or should I call doc tomorrow? ?
Also, is it even normal to still be having a period?
Thank you x
