round ligament pain but not pregnant?

I keep getting round ligament pain in my inner right thigh crease like where your privates and leg meet that line it just shoots up into my hip. I had this when I was 11 weeks pregnant. I'm not pregnant anymore though it's been almost 4 months I got my period 7 weeks after my d&c and then the depo on April 24th which was day 3 of my 7 day period. Is this normal to still have after the pregnancy? Or can I just have it just because? I never experienced it til I was pregnant.
