Many women find their early pregnancy symptoms very difficult to cope with at work (morning sickness, exhaustion, frequency...!) And it can be particularly hard to keep your pregnancy a secret if you are regularly running to the bathroom to throw up. Depending on your individual circumstances you may want to tell your immediate boss, or a close colleague in confidence. If you work in an area or occupation that may be hazardous to you and your baby, ask to be moved to a different job during your pregnancy, or investigate what health and safety measures can be put in place.
As your pregnancy progresses use your common sense. If possible try and keep your feet up, by placing a box or low stool under your desk. Take regular breaks from your normal position e.g. sit down if you stand for your job, or stand up and stretch if you sit. Keep hydrated. Make sure you have a bottle or glass of water nearby, and drink and refill it often.
Dress comfortably – and in layers; It can be a long day, and you may need to strip down as you heat up. Invest in comfortable shoes, and consider wearing support tights – or at the least maternity tights.
