What Causes Sharp Pain In The Vagina; Area?

I have had some sharp pains in my vaginal area. Sometimes just a dull pain, feeling of something there, and then every once in a while it is a sharp pain. 35, not pregnant.
Could this be from a pulled muscle. I am very active, a runner and stretcher (yoga). This happend about a month ago and went away. I now feel it again, during ovulation. Could that have anything to do with it? It does not seem normal and other women I have talked to have not had this.
