Normal ba na matigas yung tyan ko, 5 months na po akong buntis

Mama, please get checked by your OB as soon as you can, abdominal tightness in pregnancy can be normal Braxton-Hicks contractions, but it's better safe than sorry, lalo na kung may pain or other symptoms pa. Your doctor can confirm everything's okay and give you peace of mind, so don't hesitate to call or visit!
