I have a tender spot next to my right hip on the inside. What could it be?

It's not really painful, just when I touch it, it kind of feels like a bruise. It's more annoying than anything else. I have no other symptoms, no nausea or anything like that. I just had my mirena iud removed 2 days ago & am now on the nuva-ring & the pain started after leaving the drs office. I'm thinking that maybe my doctor pushed down too hard during the exam & bruised me under my skin but I'm just trying to get insight from others. My biggest fear is that it could be my appendix, but I think the spot is located too far down to be my appendix. Thanks in advance for your input :)
