Perut senak malam-malam memang biasa sikit masa pregnant, terutama bila dah mula uterus membesar, tapi sebab ni first baby ko, better check dengan doctor je untuk peace of mind, a few of my mum friends jugak ada similar concerns awal-awal pregnancy dan doctor dorang semua reassure mereka it was normal. Bisa jadi gas, constipation (sangat common masa pregnant!), atau just the stretching, tapi good to rule out anything else dengan proper check-up. How long has it been happening?
