is it normal for nexplanon to hurt?

Haley
I really need advice. I am so scared and don't know what to think. I got this a little over a month ago, I had bruising the first week or so but never swelling but the last couple of days my arm has ached either near the implant or somewhere else on my arm.. and I just had sex a couple days ago and the condom broke before he came but some could have gotten into me.. so I'm scared that if it's hurting what if it's not working? I can feel the implant and it doesn't seem to have moved but honestly is this okay??? I am so nervous and anything would really put me at ease I am seeing the doctor in a few days I just wanted someone to talk to about this because it's really making me scared right now.
