Aww mama, yan talaga common sa third trimester because of hormonal changes and swelling! A few of us tried moisturizing regularly with unscented lotion (okay din ang coconut oil), and avoiding super hot water when showering helped lessen the itching, pero if it's really severe and keeping you up at night, better check with your OB na kasi sometimes pregnancy-related itching needs proper checking, maaga pa lang kayo sa 30 weeks pa lang so mas okay if addressed na. Hoping you feel better soon, preggy itches are the worst!
