    • The nauseating symptoms of morning sickness here. Try ginger, vitamin B6 and even acupressure bracelets to help relieve the nausea.
    • You're still experiencing mood swings. This is totally normal given how your hormones are surging. 
    • You’ll be very fatigued at points as your body draws nutrients in to feed your little one.
    • You will feel like you need to pee all the time, but at the same time, you need plenty of fluids to stay hydrated just avoid too much coffee.
    • If you’re getting headaches, it may be from hormones or just your body adjusting to changes in posture. You can still take acetaminophen if you already do.
    • If you’re still feeling nauseous from morning sickness, try foods that contain ginger, ginger ale, or ginger lollipops. Also try foods that are bland and low in fat
