Gap between 2 visits in the USA - B2 Visa ( Canadian Permanent Resident)

I am a Permanent Resident in Canada. Have been here since July 2014. I got a 10 year B2 visa in August 2015 (I am currently working full time). In Sept 2015, I went to the states for a wedding - came back to Canada within a week for work but the stamp on the passport showed i could have stayed until May 2016. If I am heading back to the States for a week this December will this be a problem? The gap between my first and my upcoming second visit is a month.
