Shooting pains in vagina!!!

Dani
I will be 25 weeks on Wednesday and today I have these shooting pains in my vagina, literally in my vagina, lol and my rectum. I am on my feet a lot for work, I am veterinary technician. I am also a first time mom. It doesn't happen often but today it was so painful and happened when I was sitting down at the computer. Is this normal? Should I go see my doctor?
