piyobaby : it's normal to experience some contractions b4 birth, but i can't rem shld it start fm 2nd trimester or 3rd... the contraction feeling is like the whole womb contracts & harden, sometimes the feeling is like the baby curl up to 1 side, then an awful shape form on the tummy... nowadays, i feel some tightness, but dun really see the odd shape yet, so i m not sure if it's contraction... i think it's ok, as long as not painful, shld not be a cause for alarm. =) Don't worry, shld be fine - unless you feel painful. =)
