So 8m about 8 weeks pregnant and I have been doing ok so far sx wise but today all of a sudden bam..nausea bad

.. I have been eating small meals/snacks saltines ginger Ale water... nothing helps. It doesn't help I have acid reflux as well which I take ranitidine for.. I keep belching and some times I belch and get acid coming up. Ugh its gross sorry Tmi.. anyway the nausea is bad and thinking of certain foods or drinks makes me want to hurl. Any suggestions on what worked for u?
