Late period

Abigail

So I need some opinions...

My boyfriend and I have been trying to conceive for about 2 months. I know the whole pregnancy thing takes time. I am 14 days late for my period but all my test that I've taken show up negative. My boyfriend told me to get a blood test. But I dont know when is to soon get one if I go. What do you guys think? Be patient or go and get one?
