Not feeling well

This is the first time during my pregnancy that I've felt this way. I'm 11 wks and 4 days.  I've felt nauseous before and thrown up before but today oven thrown up 4xs and I feel really off. Super light headed, groggy, on and off headache, fatigued, my legs feel like they weigh a ton. I took my blood pressure and the highest it got was 135/85 it's been around 12x/7x before and after lunch. I had a banana and fruit smoothie for breakfast, Peruvian chicken for lunch, threw up a couple of times so far. Not sure what to think. I'm eating ice chips right now and I feel super cold, but a little better... Any suggestions?
