discomfort and pain

hey everyone, I don't think there's any other way to say this than just straight forward so I hope someone can help me figure out what's going on... this is my first pregnancy and I'm in my 3rd trimester. however, I've been feeling pain/soreness in my groin area.. no I'm not sexually active and I don't have any infection. I was wondering if anyone else has gone through this, what does it mean, is it normal, and what can I do about it?

please, help me if you can. I don't want to go the doctor if there's no reason to.

thank you.
