I am a teacher, and have had to sit outside in the sun for quite a while this afternoon for Sports Day. It is the fete on Saturday and I am running a stall, meaning that again I will be out in the sun from 2 'til 4. There is no way I can have more than one break when running the stall, it is always manic! I'm 5 weeks pregnant and had a MMC in December, so I know I'm super cautious, but am I being ridiculous to worry about this?
