Is this baby or Braxton hicks?

Me

Ok, so basically when I go pee it feels like my baby drops low and out forward and my belly is more firm than usual up a tiny bit passed my belly button. It stays that way for maybe a minute or less and then usually comes back 5minutes later or maybe a little less for about the same time period. Is this Braxton hicks? I am 24.5 weeks first baby and it's been happening about a week. First few days it happened I thought my baby was doing it but when I push and rub it doesn't change until 30 or more seconds.
