Never had a false negative in the 120 day test when I've waited past 120 days that is. I hope she is pregnant, you should be able to feel baby kick by now for certain. Put your hand just in front of her udder at mealtime. You will feel a kick right into your hand or maybe a series of kicks. If you feel nothing for several meals, she is likely not pregnant. Mine are all at days 193-208 today and rarely a meal goes by that I don't feel some sort of movement.
