mole from small and flat to bigger size durig pregnancy

At first i thought it was kinda weird, pero just now after ko maligo napansin ko din na yung mole ko sa gitna ng breast (na dati namang flat) eh, elevated ngayon as if buhay na nunal na nag elevate. Yung lapad/diameter nya is just the same pero now umbok sya. Never thought it was about pregnancy kaso i find it so weird kaai buong buhay ko flat to and i am now 28. Ngayon lang as in today ko lang sya napansin talaga na umbok sya so i searched this app, and i think i am not alone. Have you consulted your OB na po ba?
