Developing placenta is anterior.

Hi mga momsh. Ask ko lang ito. Currently on my 10th week. Last Dec 23 nagrequest si Doc magtransv ako dahil around 6pm ng Dec 22, may discharge akong parang light yellowish brownish fluid. Then ayun nga, pagtransv, anterior placenta grade 0, lowest edge totally covering the OS nakalagay. Question: naiiba din ba position ni placenta while lumalaki yung baby? TIA.
