Oh you poor thing! The last thing you need. And it sounds like you took perfect precautions - cooling, freezing, reheating.

It just goes to show, you be so careful with what you eat and still have a dodgy moment. In my research on sushi in pregnancy, I came across SO many women who got FP from dodgy burritos, stew, a baked potato etc. - yet no one is warning women off burritos! Just a spot of bad luck I'd say - I hope you are feeling better soon!
