Contractions lasting longer than 4 minutes??

I have the bloomlife contraction tracker and I’ve just got a notification saying I had a 4 minute contraction. I felt it and I tracked it manually and got it for 4 minutes as well. I had one that lasted nearly 5 minutes yesterday and called my doctor and she wasn’t much help. She said that my tracker must be wrong. That’s why I’ve been manually tracking too and they’re still this long. I person thought maybe I was dehydrated but the days not even half over and I’ve had 36 ounces out of the 64 I drink a day. Have any of you had contractions that lasted this long?
