As the future mother Meghan is learning, the first trimester, and often beyond, can be unexpectedly exhausting.
Obstetric consultant Maggie Blott said: "During the first half of pregnancy, particularly during the first three or four months, many women experience extreme fatigue, in part because the body is working very hard.
& # 39; A baby grows faster in the first three months of pregnancy than at any other time, so a woman needs a lot of energy to support that growth.
The pregnant Meghan, who is expecting her first child next spring, was beaming in a black evening dress with what appeared to be a feathered detail. The future mother assisted in the afternoon after taking the morning off to rest
You also expect some pregnancy hormones to be higher during that period, which can also contribute to extreme fatigue. It is the way nature ensures that a woman slows down to allow the body to focus on the growth of a baby.
Extreme exhaustion can often cause recurring symptoms of nausea and vomiting, and the only thing that can be done in that situation is rest.
Anyone who has worked and been pregnant knows how difficult it can be to get up when the alarm goes off in the morning. And the only way to deal with this is to go to bed early at night.
Regarding jet lag, Dr. Blott said that pregnant women may take longer to adapt. "I tell women who travel: Be patient, it will take a little time."
But should a woman embark on an exhausting work schedule while she waits?
Dr. Blott said: "Look at the doctors who work until they give birth, lawyers at the court, they all have busy jobs, so it's not crazy."
