Started to feel sick

Helen

I am 18 weeks and 3 days and for the past two days I have felt sick every time I eat. I was in hospital for a couple of days with really bad pain, I am home now and still in bad pain but nothing they can do. Could it be to do with the pain or is it morning sickness which has started late as never had it before. I just think its strange as its only when I eat. It lasts a bit after eating as well.
