Ay possible talaga na may regla ka pa while pregnant, lalo na sa early weeks, nangyari din sa akin with my second! Pero usually lighter lang siya or different from your normal period, kaya best talaga mag-take ng pregnancy test or makipag-consult sa doctor para sure, especially if parang unusual yung flow mo or may cramps na hindi normal. Hindi rin exact ang timing ng when you'll know, some people alam agad, others parang weeks pa bago nila ma-realize hehe, so if suspected mo na buntis, go get checked na lang para hindi ka mag-stress wondering!
