Aihhh sayang, morning sickness or nausea at 7 months boleh jadi tanda ada something yang kena check, please go see your doctor or midwife, okay? Jangan tunggu lagi especially kalau dah lesu badan. A few of my mum friends had the same issue at that stage and rupanya ada reasons yang doctor perlu tengok, so better safe than sorry! Let me know macam mana k, sending you lots of energy. Take care!
