"Initially,I was drawn to the paragard for the lack of hormones and longevity.I've had my IUD for about two years now, and while it has been extremely effective, it really hasn't been a walk in the park for me. Insertion was an absolute bear. I've never had children and the OBGYN I saw said that would make insertion a bit more painful. She was right. I spotted for the first month or so and that stopped after my cycle regulated. Now, I cramp at the start of ovulation through the entirety of my menstruation. My flows have gone from light/regular  to super/super  . The cramps vary from being manageable with ibuprofen to nothing being able to touch them. I don't know that I'd recommend it to women who haven't had children yet."
