itchy during pregnancy πŸ€’

Is moderate itchiness with no rash normal during pregnancy? I'm currently 33 weeks pregnant and I've had like the most bothersome annoying itching all over my body, but no visible rash just redness from scratching..I called in to my Dr. and he doesn't seem worried they think it's most likely an allergic reaction,but I've taken benadryl and the itching still persists so much so that it's hard to fall asleep at night now..if anyone has any idea what it could be let me know 😯
