Second trimester & morning sickness is through the roof!!

So my doctor told me yesterday, that I hit my second trimester. Today I'm 13+4. I'm just getting over a cold and since last week my nausea and vomiting has gotten worse. I left work twice last week, called in Saturday, left early Wednesday, and just now left work again. All because of this morning sickness. I was only nauseous during most of my first trimester. Now it's hit me harder than a bus and that's exactly how I feel. And today, I'm really light headed. Ugh!!!
