What is it?
The shot contains the progestin hormone and is given to you by a doctor or nurse. It only works if you get the shot every 3 months (4 times a year). Progestin stops your ovaries from releasing eggs, and changes the chemistry of your uterus, making it harder for sperm and egg to find each other and survive. Once the shot is given, it keeps working until it wears off (3 months). You don’t have to remember to take it as often as the pill or the ring, but it’s not the best option if you’re freaked out by needles.
