I'm 19 and I payed at planned parenthood for my IUD mirena. It cost me around $856 really expensive if it wasn't for me having two jobs, I wouldn't had been able to buy it. I'm leaving to college and wanted to be safe about the whole situation. I've spotted almost every day, it's been 1 month and 2 weeks spotting has gotten lighter. By boyfriend is weirded out by the strings. So sometimes his iffy about having sex, but the strings have soften up so I've heard less complaining. Sex love is enjoyable now not having to worry about the pill, pull out, plan b.  Great investment to my life regardless of what I read. I was on depo for 9 months I was a complete bitch. The pill made me prone to yeast infections. Since mirena I've been having a smooth ride.
