birth control
"So yes it's effective, BUT NEVER GET THIS SHOT. I had it 3 times (9 months) worst nine months of my life. Constant spotting and bleeding, never was able to go on the boat because I didn't have enough bleeding for a tampon but would bleed threw a bathing suit, felt very uncomfortable and always had to think about if I was bleeding, never wore white bottoms or pants. It was THE WORST experience of my life. If you see this DONT TAKE THE SHOT."
