Levonorgestrel
"I had terrible experiences on Alesse & Ortho Tri Cyclen so my doctor recommended Skyla (Jaydess in Canada) over Mirena for me because it's both smaller & releases a lower hormone amount since it lasts 3 years vs. 5 for Mirena. After reading the reviews here I was worried but wanted to try it anyway. There was a HUGE cramp after she measured my uterus & inserted the IUD, what I imagine a contraction feels like. I had lots of cramping afterwards for 2 weeks & on & off spotting for the first 3 months but that's all gone now. I'm really happy with Skyla, but every body is different.



Pros: shorter, lighter periods; no mood swings; no weight gain; no acne; no loss of sex drive

Cons: slightly worse pre-period cramps; occasional post sex cramping"
