My period was tailing off at the beginning of the week, and I forgot about it and left my mooncup in for 24 hours from Monday - Tuesday (the last time I used it). I've had a terrible headache and a bit of nausea since yesterday morning, and got up to be sick a couple of times in the night. That's it though - no fever or any other symptoms at all. I'd be wasting the GP's time wouldn't I? It sounds more like a bug, though I have no idea where I'd have got it from as I haven't been anywhere. I thought TSS came on quite suddenly but I've been feeling the same for 24 hours now. Would you call the GP or not?
