birth control
"I had skyla for about 4.5 months.  I was super excited as I am very sensitive to birth control pills.  Insertion was VERY painful and my doctor was great as she talked me through the whole process.  I went back in for my 1 month check up I said that spotting only lasted 4 days.  I had poking pain on my left side that never went away.  After month 3 which I stuck it out she couldn't find my strings,  I got an ultrasound apparently my cervix is narrow even for skyla. That's why it was poking me.  Brown Periods lasted for 1.5 weeks after 4 months.  I got it out today and the poking stopped.  Back to square one. Everyone's body is different.  I wish it worked for me!"
