Momsh, normal talaga yan during pregnancy kasi ang hormones natin ay super active, pero depende pa rin sa severity at kung itchy or painful ba! A few of us mommies experienced something similar around that time, and mine cleared up on its own after a few weeks, but one friend namin had to check with her OB kasi it was getting worse. I'd suggest mentioning it sa next prenatal visit mo para ma-rule out kung may ibang cause, and in the meantime avoid perfumed products sa face area para hindi mag-irritate pa more.
