Braxton hicks at 31 weeks

Alice
Hey ladies so ill be 31 weeks tomorrow and the last week or 2 ive had mild cramping during the day but the last 2 nights my whole stomach has become so hard and tight it wakes me up at night? No blood or fluid leakage or change in discharge or anything. And little girl has been extra active. Idk if she is trying to turn because she was breach last sono or its Braxton hicks but anyone else???
