Mirena
"I was considering changing over to the implant because the insertion process sounds easier but after reading THOSE reviews...I think I'll stick to my Mirena.

All in all I love my Mirena. It will be 4 years this month since I've had it. I haven't had a period in over 3 years. Occasional spotting. Rare cramps. I haven't noticed any mood changes or acne or anything else people are reporting. My bf has never noticed when we have sex and there is no discomfort for me before or after. The ONLY thing I would say was not very pleasant about the Mirena is the insertion.  Probably the most painful thing I've ever experienced thus far (32 yrs old, never been pregnant/given birth). Lasts a sec tho. All in all, highly recommend :)"
