I'm 17, and
recently became sexually active. I decided to go on depo
to protect myself from pregnancy. I got it on Nov 4 2011, I experienced no symptoms until Dec 6 2011. I started spotting, at first it didn't even require a pad or tampon. It gradually increased and stopped occasionaly for a day or two, I gained 10 pounds and started getting horrible headaches, right leg pains, loss of appetite, painful intercourse(before the bleeding), and mood swings. Now the blood is regular period blood.
