Women during week 33 of pregnancy may experience fluid leaks. The American Pregnancy Association explains that many pregnant women at this stage leak urine due to the pressure placed on the bladder, but it could also be amniotic fluid leaking. A fluid leak is not a major concern unless the amount is large enough to indicate a premature rupture, in which case, the woman should seek medical assistance.
WebMD explains that a mom-to-be may experience less large fetal movements starting in week 33 because the baby has less room to move as it gains weight. Although the baby has less room to move and is unable to make large movements within the uterus, What to Expect explains that the mother-to-be may experience sharper pokes and kicks from the baby. As the ratio of fetus to fluid change, the fetus becomes closer to the woman's body. The woman may feel more uncomfortable as her body makes room for the growing fetus.
Another major symptom during week 33 is insomnia. What to Expect explains that three out of four pregnant women experience insomnia during the third trimester. Anxiety, baby movements, the need to urinate, hormonal changes, leg cramps and heartburn often cause insomnia. All of these symptoms continue throughout the remainder of the pregnancy.
