Braxton hicks Vs. preterm labor?

Alex
What have your doctors said about contractions? I wasn't too fond of the last dr I saw and I told her I had been having strong Braxton hicks for two days in a row. Didn't seem to care at all. Which somewhat understandable because they weren't painful. But I went into preterm labor twice with my son so I'm a little paranoid. I asked her when I should worry and she kinda just gave me a vague answer that I can barely even remember now. Currently I have been having contractions for a few hours. Seem to be getting closer together but I hadn't been keeping track until now because I just figured Braxton hicks. Not painful at all. I don't want to worry for nothing and then again I don't want to go into preterm labor like I did with my son. Plus it's been a few years so I kinda forgot what it was like to go into preterm labor.
