Dull Pain on Right Side

Lara
I'm 7+4.  Yesterday morning I woke up with some intermittent, dull pain on my right side - not low, closer to mid-upper stomach, like belly button level.  It continued through the day (I'd notice it every 20 mins or so) and it seems to be continuing today.  It's nothing severe, almost more of an annoying pain, no cramping and no spotting.  Of course ectopic is on my mind but it doesn't seem like my symptoms are consistent with it.  Gallbladder maybe?  Anyone have experience with this same pain?  My first Doc appt is Monday.
