I'm sitting at home feeling super guilty as missed work yesterday and could only last until 1300 today. Just felt awful - like being very drunk, room a bit spiny, very sick but only dry retching (tmi), not bale to concentrate on what was going on but now I'm home and on the sofa I feel ok. Could this be stress? Work is pretty stressful at the mo so wonder if that is linked?? I feel like such a fraud not working as I'm not ill and obv can't tell people I'm preganant. Is this normal?
