How I'm feeling at 12 wks

I hate being a whiner.....but woah! I feel like I've gained 20lbs, but I've actually lost 5lbs from pre pregnancy weight! I'm so bloated....also I have zero energy....I've been getting 8-10 hours of sleep every night, but can't even scrape off my car for work without feeling exhausted. I pee like 5 times a night lol have killer heartburn, and I'm always hungry, but I'm full after very small amounts. .. is this all normal? Does it ease up or am I in for a long 6 months? haha how are you all feeling?
