Is it normal to have heavy clotting during a menstrual cycly?

I don't know if it's normal, but I have clumps in mine too, and so does my best friend and my mother. So I wouldn't worry too much about it. Talk to your doctor about it. I went to planned parenthood for my birth control, and they answered all of my little questions about those kind of questions.

It's normal for some women, and can be a problem for others. For a proper diagnosis it is imperative you speak to your doctor about this.
