Juliette's pregnancy tests that she took were actually negative, and she actually told Rosalee that all three pregnancy tests that she took were negative in Chupacabra. She also told Nick later in Bad Luck that she thought she was pregnant and that she didn't know what was happening at first when she was starting to turn into a Hexenbiest. Unless she actually became pregnant from Kenneth, it's really doubtful that she was; plus, Henrietta would have detected something like she did with Adalind when Adalind came to see her.
