Have I got food poisoning?

Earlier today roughly about six hours ago, I ate some raw cake mix. I also had a sausage cob and the sausage was very slightly pinkish although the outside was thourghly cooked. Then about an hour ago I got very severe stomach cramps, chills, became sweaty and very nauseous and thought I was going to vomit(I didn't but I felt like I needed too) it lasted for at least half an hour and then went completely and I feel fine, maybe a tiny bit nauseous but nothing serious. But now I have stomach cramps again, like period pains and constantly needing the toilet and have diahorrea. Do I have food poisoning? If not what else could it be?
