Can You Get Pregnant On The Shot

Hey there,
As far as i know the shot is supposed to be 99.9% effective. If you are unsure take a home pregnancy test if you have missed a period or have had an abnormal period. I have known a lot of people who have tried the shot and it has done some strange things to them. My sister would go four months without a period, one cousin gained a lot of weight and my aunt had problems getting pregnant after she stopped taking the shot. Of course there are those who have had more success on it. If you are unsure it is always best to call your ob/gyn or a pregnancy clinic in your area(most will do a free pregnancy test for you). Sore breasts could be the result of different things also such as your hormone level during a period or even excess caffeine. But of course it is always best to know so i would urge taking a test to find out plus you will relax more once you know. Good luck!
