I've had a Kyleen spiral since December 6th; After putting it on in the middle of the cycle I have terrible nipple pains and I have terrible spotting, plus stomach pain - is this normal?

The side effects you describe may be due to the Kyleen spiral (because I assume you meant this product). During the first 90 days after insertion, more than 50% of women observe the prolongation of menstruation, and more than 40% - irregular bleeding. Other side effects that can occur very commonly are headache, pelvic abdominal pain and breast discomfort. Bleeding will decrease over time – by the end of the first year, about 25% of women using Kyleena report a decrease in menstruation or no menstruation. If side effects in the form of breast tenderness or abdominal pain persist, it is worth seeking advice from a gynecologist.
