I'm seriously having to get up about every 3-5 min to pee, and haven't even drank anything in over an hour! I'm about to lose it, I've been trying so hard to go to sleep for about 4 hours, either I'm itching too much, baby is making it too uncomfortable, my head hurts, and now this! I'm about to cry man 😭😭😭
