N.G.
Congrats! I'm six weeks along, and thank goodness not having many symptoms.
Nausea wreaked havoc on my life for my first two pregnancies. My saving grace was dry cheerios before getting out of bed in the morning. I found that the nausea was caused by mucous dripping down the back of my throat- and the cheerios would help soak up whatever was in my tummy in the morning. It worked absolute wonders. Just one handful before getting out of bed. Eat it, let it sit for a minute, then go about your day.
Hope that works!
