Please answer, Im so freaggin miserable!?

In my first trimester I was only nauseated and not really throwing up. Now that I am in my second trimester I notice every time I get my stomach empty I am tasting bile and this morning it made me throw up 3 different times. I keep having this nasty sour taste in my mouth and it doesn't go away till I puke then Im good for another couple of hours or so. I thought nausea was supposed to go away after the 3rd month, mine seems to be starting. I am doing preggo pops, Ginger Ale and lots of water but nothing is soothing the nausea. PLease give me some insight if you can, Thanks and Merry Christmas!
