pain... contractions?

Heather
Over a week or two I have had pain when I bend over, pain is somewhat sharp and feels like it's in my vagina. Recently the pain will happen when I don't do anything. 
I'm wondering if they are Braxton hicks. Or real contractions. I'm a FTM. Not sure of what real contractions feel like. I ha e a high pain threshold and don't complain about pain. But I don't want to ignore something I shouldn't.
