Help?

Ok I'd like I little help, I mean I know you guys can't diagnos me through the screen but it'd be cool if anyone could give some insite on what's going on?

I've been having this pain (not too bad about a 5-6 on a 1-10 scale) on the right side of my uterus and it shoots down to my knee, it started maybe three weeks ago, so about a week before my last period (also side note I was two weeks late on my last cycle) now I'm having my usual ovulation pain just a little more intense than usual and only on the right side and today I noticed that the area over my right ovarie is firm, not really hard but it's fairly firm and the other side is not. I'm just a little concerned and not sure if I should ask my mom to take me to the doctor (I'm only 16) I feel silly asking on here but I don't really have another option (I'm reposting because I couldn't see any of the comments on my last post)
