This magic wand uses sound waves to make pictures of your baby + your organs. You’ll have one, at a minimum, three times. You’ll have it once at the beginning to see how far along you are. Somewhere between 11-14 weeks, you’ll have one so docs can view the back of your baby’s neck. Folds or thick skin there could mean a higher risk of Down Syndrome. (They’ll also sample your blood at the same time) Then, at around 18-20 weeks to check your baby’s growth + organ development. If you’re having a more complicated pregnancy, you may get more ultrasounds + more chances to see babe!

Umbilical Cord

/uhm·bil·i·kuh·l· kawrd/

The umbilical cord connects a baby in the womb to its mother. It connects via the placenta to baby’s stomach in order to get your babe oxygen and nutrients and to remove waste into your bloodstream. After deliver, the cord will then be cut (there are no nerves so this isn’t painful) leaving a 1-1.5 inch stump on your baby's tummy, which, when healed, will form your baby’s belly button. Your midwife will usually cut the cord or, sometimes, you or your birth partner can do it.

A urinary tract infection (UTI), or bladder infection, is a bacterial inflammation in the urinary tract. Pregnant women are at increased risk for UTI’s starting between weeks 6 and 24 because of changes in the urinary tract. As the uterus grows, its increased weight can block the drainage of urine from the bladder, causing an infection.
