"i&#039;ve had the slyla iud for 4 months now and the first time i got it i had really bad cramps, dizzy and was sweating like crazy.  when i get my period i get the worst cramps of my life. the cramping lasts about 3 days which heating pad and motrin has helped a bit. i&#039;ve had light spotting for 3 months which makes it difficult to have intercourse with my boyfriend. i&#039;ve gained about 10 pounds. not too satisfied but not kids so far which is a good thing."
