The amount of time it takes a woman to get pregnant after being on the Depo shot for contraception doesn’t necessarily depend on how many doses you received. You mentioned that you were only on it for three months. It’s largely dependent on your weight. They’ve shown that women who are underweight or normal weight will return to fertility faster than women who are overweight. So if you have more questions about it, it would be best to talk to your doctor because they have knowledge of your health history, your weight, and your previous forms of birth control and can give you more specific answers. But if you have any more questions for me in the future, feel free to ask them on our Facebook page at facebook.com/intermountainmoms and recommend us to your friends and family, too.
