Last night I had a dominoes pizza for dinner. About an hour ago I ate the last two slices cold from yesterday which had been left on the side all night. I've done this before not being pregnant and had no issues but now I'm worried about it being 7 weeks pregnant. Am I ok ? I've just realised it wasn't even put in the fridge.
Try not to worry. As pp said, ypu shouldn't make a habit of something that has sat on the worktop all night but that's true whether pg or not.
The NHS website has a very comprehensive list of what you can and shouldn't eat and it's really nowhere near as restrictive as you might think, particularly as it also gives the workarounds. For example, I still have sushi once a week as the fish has been frozen first.
Most miscarriages are a result of something wrong with the fetus, not action by the mother. Relax. The human race would have died out a long time ago if pizza on a counter was all it takes to end a pregnancy.
