ETA: thanks ladies for your quick and great responses. I called the OB on call and he said to just keep track of it. If it doesn't go away, if it's gets worse or contractions become stronger/regular, then to head right into L&D.
Sebastian Joseph made it into this world at 12:44 AM this morning 1/26. He weighs 7 lbs 13 oz and measures 20". Both he and I are doing wonderfully! Pics in replies!
