So I have the implant birth control and the only real reason why I have had it for 2.5 years is because I'm so sexually active w my bf. I spot a lot after my periods for a couple of months and there's months w/ out sporting. Is that normal? They are dark brown spotting and it is scary. Also my back has hurt more since implants birth control. My boyfriend sits on my back to ease the pain. Is that bad? I feel like when I'm bloated and he sits on me, my stomach doesnt hurt anymore. I'm just confused what signs to worry about w/ this birth control. I'm always thinking I'm lowly dieing.
