Ok, I just had the implant removed due to it hurting my arm really bad I was on it for almost 2 years. Had sex with a condom the next day after it was removed. Now I have been having lower back pain, abdominal pain and it also feels like I have to poop but don't when I go to the bathroom. When I do poop my butt hurts after.I've also been stressed for a few weeks. I think it's just stress and me worrying that I did a stupid thing by having sex the next day after I got off birth control
