During this period, you barely feel you are pregnant and may experience cold-like symptoms, high basal body temperature, and physical fatigue. It should be noted that: 1. Once you are diagnosed with pregnancy and plan to have a baby, you should explain it to your unit leader and colleagues as soon as possible so that you can arrange work. 2. Remember: Do not use cold medicine indiscriminately. Get some rest as soon as possible after returning home to ensure good working condition the next day. 3. If you still feel tired at work, you can explain the situation to your leader, take a short nap, and replenish your energy. 4. In addition, if you work in an office for a long time, you must take time to walk outdoors every day to replenish oxygen.
