Blur, and tiredness

6 weeks+ pregnant with Two. Blur and tired. Stuck my ezlink card at the back of my denim shorts pocket and promptly forgot about it when I reached the bus stop. I thought I had forgotten my card and used coins instead. Only at alighting then I realised that my card in at my back pocket! Tired, could doze off in a bus and was so lethargic when I woke up.
