Am 27 weeks and seem to have hit a brick wall of tiredness! I am sleeping okish but get in every eve and six and have to go to bed! I can't concentrate at work and have felt a bit faint and lightheaded a couple if times. I don't know if this is normal and I am just bring a wuss or should I go and see GP. spending 2.5hrs a day commuting doesn't help. Am seeing MW next week anyway but starting to feel hysterical!!
