For about a week now, workman at the house across the road have been burning rubbish as they've been doing some work on the house. I'm not sure if the neighbours are even actually there at the moment. It's so strong that my whole flat smells of it. However, I keep thinking, oh well, the smell is not that bad, and surely they will run out of stuff to burn soon.
However, since they have started, I have had a constant headache and wonder if this might have something to do with it? I never normally get headaches and this one just won't go away. However, I am also a week overdue (unusual but not pregnant) so the headaches could be related to this.
