Day 148 of 280, second trimester
You are 21 weeks and 1 day
If you often walk into a room and forget why, don't worry; you've just developed "pregnancy brain"!
132 days until your due date
Is your mind not as sharp as usual? Many women get frustrated by "pregnancy brain," which can make them so forgetful they lose track halfway through a sentence, and can affect concentration too. Doctors aren't sure why it happens, but it's probably down to hormonal changes. It may also be because you're focused inward: with such a major life event and so many changes to your body and lifestyle, you simply pay less attention to other things.
Frustrating as it is, the forgetfulness is temporary (although it may last into your baby's first year). Meanwhile, make a list at the start of each day and tick things off as you go. Delegate at home and work where you can, and for once, don't multitask; focusing on one thing at a time will help you remember and get more done.
As a matter of fact
Pregnancy brain can linger
"Pregnancy brain" may last until your child's first birthday.
This is based on research around the world; after in-depth analysis, experts concluded that lack of sleep in the first year of parenting may play a part.

Write it down
If you're more forgetful these days, write things down and prioritize so you don't feel overwhelmed.
Ask a Doctor
I've always been a keen walker. Should I cut back now I'm past halfway?
No, but take a few extra precautions. Walking is ideal low-impact exercise you can keep up throughout pregnancy, and it's especially good later on because it doesn't jar your knees and ankles.
If you like long, brisk walks, mix in a slower pace. Avoid overheating by drinking plenty of water and wearing layers you can take off and put on.
As your belly grows, hills and uneven ground may make you unsteady, so stick to level paths, and take frequent breaks if you get breathless. Always wear good, sturdy shoes and avoid carrying heavy loads.
