What Are the Symptoms When You're 11 Weeks Pregnant?

What to Expect says that pregnant women in their 11th week experience bloating, gas, excessive urination, breast tenderness, fatigue, nausea, vomiting, excessive saliva, food cravings, food aversions and fainting. The hormone progesterone is responsible for the bloating and gas as it relaxes the digestive system and slows down the digestive process for optimal nutrient absorption. The side effect is abdominal bloating and increased gas.

Pregnancy fatigue during the first trimester is normal. What to Expect says during the next few weeks the body is developing the fetus and placenta, which results in all-day fatigue. The fatigue reduces for most pregnant women in the second trimester once the body is adjusted to the new routine. Morning sickness is still present during week 11, but most mothers-to-be can expect the nausea and vomiting to disappear between week 12 and 14. Not all women are so lucky, and some pregnant mothers experience morning sickness throughout the entire pregnancy. During week 11, urination becomes more frequent as the levels of hormone hCG increase, and it increases the blood flow to the pelvic region and the kidneys. Some pregnant women begin to show a little bit during week 11, but every woman shows at a different rate.
