Contractions?

Nicole • Been married to the love of my life for almost 6 years. We have been together for 13 year. Our baby girl is now 11 months old
Where do u feel the contractions or braxton hicks pains? Is it more in ur stomach or in ur vagina? I have been having on and off stabbing pain down there and was wondering what it could be. I will be 36 weeks tomorrow.
