I would try the pill. I enjoyed being on the pill, I stopped because I wanted something less frequent. So I went to the shot worst desist on ever plus it can take up to a year or two to get pregnant, it can cause firtility problems. The side effect plus the firtility  thing was enough for me to not go get my 3rd shot. On my first shot I bleed the whole time, on my second I didn't bleed at all but I was nausus, moody, and had headaches all the time, plus my acne went out of control. I will never recommend the shot to anyone. 

Different bodies react different i would pick one and try if it doesn't work like you have bad side affects choose something else =)
