Princess Charlotte has only been seen officially in public twice. Princess Charlotte has made her first public appearance on the balcony at Buckingham Palace. At 13 months old, Charlotte is almost the same age as the Queen was when she first appeared on Buckingham Palace's balcony 89 years ago.
For most women, morning sickness starts about the sixth week of pregnancy, which is about three weeks after conception, assuming you have a normal menstrual cycle. It can start as early as the fourth week, which is right around when you might get your period.
Nausea -- that is a huge variable. Some people have it all through pregnancy, some not at all. Typically, the worst nausea's after you wake up, whenever that is, and generally ends after the first trimester. One thing to check if you're having violent nausea, though, is your prenatal vitamins. For some people (like me) they're so strong that even if you take them with food, you can't keep them down.
