Levonorgestrel
"I've had the mirena IUD for 5 months now and so far I've loved it!! I haven't had any weight gain or acne symptoms that everyone talks about in their reviews. I bled for maybe three days after the procedure and haven't had a period since. The procedure sucks but its bearable. It felt like intense cramping for maybe a minute then it's over. I suggest taking 800mg of ibuprofen before and after because I did have cramps and dizziness for the whole day. I switched to mirena from oral BC because oral BC made me absolutely crazy (crying at every little thing, irrational, emotional, blowing up at people for no reason, ect) ladies DON'T LET THE REVIEWS SCARE YOU because every body reacts differently.. you truly have to try it out for yourself!!"
