Oo naman, totally normal yan! At 35 weeks, ang katawan mo talaga ay overwhelmed na sa hormones at the weight you're carrying, plus ang baby is taking up so much space na nasa lungs mo pa lang sometimes, kaya napakahirap huminga at matulog. A few of us in my mum group were literally sleeping sitting up or on our sides with pillows everywhere, dahil the fatigue was real but so was the discomfort. Just rest as much as you can, stay hydrated, at try light walks if you can, pero mostly, your body is just preparing for labor, so honor that antok na antok feeling. You're in the final stretch na, mama!
