2 second pregnancies

Rayne • Rayne 💕
So my first was easy little sickness at the beginning no growing cramp or Braxton hicks mild pressure towards the end.... this one no .... 29 weeks still getting sick, not as bad but still .Braxton hixs, cramping so bad feels like my atomic is tearing, pressure, back pain, so tired always.  They say every pregancy is diferent but shouldn't my body be ready? Any other  second time moms experience this my doctor says it's normal in second pregnancy
