"depo provera did a good job at protecting me against pregnancy. but i gained a lot of weight!! i didn&rsquo;t gain much for the first 3 months i had it. although, after about 6 months (2 shots) i noticed a significant amount of weight gain, and after almost a year i gained about 20-25 pounds.  i was exercising, and changed my diet and nothing happened. the irregular bleeding &amp; other side effects were minor side effects to me. the weight gain was my major concern. after reading all of the other reviews for depo, i saw a lot of other women had issues with weight gain too, so i switched to nexplanon  (implant), and for me it has had the same side effects as the shot but without weight gain. i&rsquo;ve been able to lose about 10 pounds since i switched!!"
