At which month do you start getting stretch mark?

so far takda strechmark. maybe sebab 1st pregnancy tapi still ambil langkah berjaga jaga sapu bio oil bila rasa gatal kat perut. orang cakap gatal tu sebab perut meregang. risau juga kalau strechmark banyak sebab bila gatal asyik garu ja. jadi awal awal jadi gatal terus beli bio oil sapu.
