Depo Shot

Cj • Going into the Navy soon. 17 graduated early

So I have this question. I’m going into the navy soon and I’m currently on the pill. I already forget to take them here and there and I don’t want to be on them when I go in. However I have ovarian cysts that cause me excruciating, crippling pain. Birth control is how I stop the pain and it works wonderfully. I’m considering the depo or the arm implant. Any advice? Would it effect pt?
