I'm on the paragard iud and they said it would make my periods heavier and crampier. It definitely did. I have to change my tampon every hour because by then it's already leaking and I can't keep doing that at my job. They won't let me get off my register every hour to do that. I'm only 21 and never had kids or anything. Is this normal? I feel like I'm losing way too much blood and I use so many tampons and it's getting expensive.
