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.
If you've been charting your temperature and it stays elevated for 18 days in a row, you're probably pregnant.
Take a pregnancy test
If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.
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.

The Cnzz.com report also discusses the problem of the 'free-to-play' business model that's prevalent in China's online game sector. While many games companies in the U.S., for example, charge subscription fees, most Chinese games utilize the free-to-play model, which allows players to try out a game without paying. The longer players stay in the game, the more likely they will be to pay for in-game items to move up into higher levels of play. But that also means that people who spend the most money are the best performers. [Accessed May 2019]
