Uy mama, yan talaga ang normal sa 34 weeks, ang bigat ng baby at hormones mo talaga nagpapagod sobra, kaya okay lang mag-rest! A few of us mums nag-worry din about staying in bed too much, pero honestly what my OB said is the key is light movement, short walks around the house, stretching, or just sitting up para may circulation, hindi pure lying down buong araw. Try to balance your rest with gentle movement when you can, pero don't feel guilty about needing lots of sleep because your body talaga ay gumagawa ng malaking trabaho! Pero since worried ka, best to mention it sa doctor mo sa next checkup para ma-check if okay lang lahat or if may something else going on.
