Its kinda hard to explain but I've been haveing a sharp pain in my vagina and lower stomach almost constant almost like pinching what could it be?

Vaginal pain. Number one: exclude pregnancy. After that the work up for vaginal pain aka vulvodynia can be extensive! Tumor and infectious causes may need to be evaluated with cultures and pap smear at the time of gynecological history & physical exam.
Hard to say. Many things can cause the pain you are having but I would be concerned about an infection. You should get it checked out.
