Colics and nausea

I had a brocoli and cheddar soup from Panera 2 nights ago and I started getting horrible stomach spasms sort or like intestinal colics (I have had this my whole life from time to pain, painful to say the least) and from all that I threw up 5 times in a row. I think because I was constipated too due to an anti nausea med I've been taking my body was trying to flush out all the bad stuff and I almost felt like I was going to faint from pain and nausea. Anyone ever experience this? I'm 8 weeks and 3 days now if I wasn't hungry before I'm scared to eat (not hungry at all either )
