Bruises , Platelet counts before periods?

This past fall I discovered in a routine CBC that my platelet counts like to hang out in the 40s-50s. I have been stable since and luckily I have yet to take any medications. I typically do not bruise, except the week before my period. This is a pattern that I have noticed for the past few years making me wonder exactly how long my platelets have been low. (I am the mom of two young kids and I missed my annual physical for a couple of years.) When I asked my hematologist about this, she did not suspect a correlation since my platelet counts have been so stable. However, I can tell you exactly what "week" I will get my unexplained bruises. Meanwhile, the other weeks, I can walk into a wall, get hurt, and no bruise to show.

Curious if anybody has ever noticed any correlations between their platelet counts and monthly cycles?

I can relate! I always had unexplained bruising a week before my period. If I saw a bruise, I knew it was on its way.

I had a hysterectomy almost two years ago, which was long overdue and something I wanted since my 20s. I had horribly painful periods and severe bleeding (along with ovarian cysts, fibroids, endo, etc.).

I’m 45, and over the past few months I have had extreme bruising - much worse than ever before, and covering my legs. It’s actually quite concerning. At the same time, I’ve started having hot flashes at night. I’m due to see a hematologist next month as my PLT count is 70,000, although it’s always ranged from 65,000-110,000, so I don’t know why that would cause bruising. I do think that the arrival of peri/menopause has something to do with it. Your question is interesting to me, because I’ve always noticed that hormonal-related bruising, but nobody can ever tell me why.
