Sakit dada dan sakit kepala memang boleh jadi normal dalam pregnancy, terutama around mid-pregnancy macam you skrang, tapi sebaiknya you mention kt doctor next visit je untuk make sure semua okay, some of my mum friends alang-alang pregnant pun ada sakit dada, sometimes it's just the hormones and your body changing, tapi taknak ambil risiko pun, so better check. Jangan worry sangat, but don't self-diagnose juga, okay?
