"So far I have had my Paraguard for like, maybe a month now. I am on my second cycle (the practitioner suggested we insert it during my period last month). It does hurt when it is inserted but 800mg Ibuprofen takes some of the edge off. Eat lots before you go and hydrate well, this helps with post insertion. I have had NO negative side effects like most. I was assuming that for one I was going to have a longer period once they inserted my IUD (it actually stopped the next morning and it was like it wasn't even in there) and then now, I just started my period today and I have NO cramps, I had no clue I was even starting. Maybe some brown spotting at first then, light bleeding. I don't even need any pain meds."
