"had the iud inserted on 08/01/2016 in august, no cramps initially but about 2 hours after the insertion i started feeling cramping but nothing advil and a warm towel didnt help with.  my periods before the iud were a maximum of 2 days and very light. with the iud, my periods are 4 days long with heavy bleeding on day 2 and 3, but a super tampon and a pad could help you with that. overall i am satisfied with the product but everyones body is different! do not let others reviews turn you away from giving this product a shot. if it doesnt work for you you could always have it removed."
