Hi louise,
I went through a similar phase for about a year after starting to take Tomoxifen my periods became very heavy & irregular so much so I didn’t want to go out, even camping which I love. I ruined sleeping bags sheets etc! I too was told it was ‘normal’. They have settled down now and I miss a period every so often (can’t wait till they stop completely) It’s the hot flushes that are bothering me now! Oh well as I say It could be worse. I’m three years into my journey, all the best for yours, Angela
