I've been having irregular but painful contractions for 2 days now and I'm tired of going to l&d. What does it mean?

Consult Ob/Gyn. At term, you are getting close to labor when contractions are frequent and painful. I you are intolerant of the pain, you need more rest, or consideration for delivery. This is a frustrating condition for patient and doctor. Continue fetal surveillance until a clear plan for delivery.
