Sorry if TMI, but I’ve always had very heavy periods, which have amped up in last few years (wear several maternity towels at night and still flood even on tranexamic acid). This is my third cycle in a row that’s come in at 21-23 days, rather than 28-9. I’m on day three which would normally mean tampon and pads and a towel beneath me in the car to get through a 45 minute school run. It’s still like the start of day one or end of day seven, hardly anything. Is such a dramatic change normal in peri? I’ll be glad if it is as my ferritin is really low and so is my iron binding, so if this helps the sheer relentless exhaustion, that would be great.
