I seriously don’t get what other women are talking about when they say certain products make them have cramps.

Prostaglandins are the chemicals produced by the uterus and causes it to contract. That’s what causes cramps. How in the world are women online saying that a product that catches blood causes cramps. This makes no sense. Woman online are talking about tampons make them have cramps. I started out in life using pads first then tampons now I’ve been using a menstrual cup for the last 8 years. I have terrible cramps and it’s not because of the products used to catch the blood.
