Levonorgestrel
"So far I've had a decent experience with mirena. I had it inserted during my period (on the 2ND day) that was a weird experience. Insertion was a breeze, no discomfort. I was nervous after reading all of the reviews.  Less than 1 minute  and it was over. I threw on my clothes and i countined on with my day like normal. I'm sure i should've waited to habe sex but i didnt. On the 3rd day i had some cramping, since then no cramping. Ive never really had much crampong so i went into a little bit of a panic mode And was beginning to doubt my decision. Bybthe next day the cramping was gone. Mild spotting.  I feel like my sex drive has increased.  I am worried about the weight gain but I plan on staying active and keep a close eye on"
