Were you late to work yesterday because you couldn't remember where you put your car keys? Did you completely forget about a coffee date last week with a friend and only remember when you got a text asking, "where are you?" Can you no longer remember the name of your favorite elementary school teacher? Memory problems impact just about everyone to a certain degree, but science suggests you might be able to improve your memory, as well as reduce the likelihood of Alzheimer's and dementia, by engaging in certain activities, eating specific foods, and using certain mnemonic devices.

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.
Tender, swollen breasts
Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.
For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.
Nausea or vomiting
Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.

Make a prenatal appointment
If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.
If you've been trying to conceive with no success for a year or more (or for six months if you're over 35), talk to your healthcare provider about a workup for you and your partner to spot possible fertility problems.
