Aiyooo I feel you lah! A few of my preggy friends kena melasma juga, mostly kat cheeks and forehead, and honestly it's more of a confidence thing than anything gatal, yang sakitnya adalah hati tengok cermin je hehe. The good news is it usually fades after delivery, especially if you're careful with sunscreen (SPF 50 minimum, reapply often), though for some mums it takes a few months.
