Go be see just in case??

I am 28 and a half weeks and was in L&D on Saturday morning for contractions that were 3 mins apart. I was not dilated or showing any signs of labor so I was sent home. I have still been having contractions off and on since then. Today they have been about 2-4 mins apart for a few hours. They are strong but I’m not in pain. I am drinking plenty of water and I have a desk job so I’m not doing anything crazy. They make me feel so thirsty. I am definitely uncomfortable but not in pain. My doctor said that if I am having 6 or more a hour I should come back to L&D.

Should I try to just wait it out and see if they let up or go ahead and go in. I don’t want them thinking I’m being dramatic and can’t handle the contractions cause I can and again I’m not in pain but they are strong. I just feel nervous because I’m only 28 weeks.
