When Sheila and Tyrone's daughter Mallory was born, on June 12. Anika was pregnant.
after she missed her period. Anika and her husband. Jeremy, were thrilled at the news,
Anika's last menstrual period began on April 3, and she's taken a pregnancy test a week
because a few months earlier she'd also thought she was pregnant. At that time, she had
started cramping and bleeding, and an ultrasound scan showed an empty sac- there was
no embryo. Anika knew from her biology classes that this probably meant that a sperm
had entered a polar body, which is a product of meiosis in the female that has very little
cytoplasm and is not the functional equivalent of an oocyte. The hormonal changes
typical of pregnancy had ensued anyway, which was why her pregnancy test had been
positive.
For the current pregnancy, at her first prenatal visit to an obstetrician, an
ultrasound scan confirms that Anika is in her fifth week. This time, instead of an empty
sac, the embryo looks like a lima bean with a pulsating blip in the center- beating
heart.
As Anika gazes at the ultrasound screen in wonder. a nurse looks over her chart
and asks about an acne drug, Accutane, that Anika had taken for several years. The drug.
a derivative of vitamin A. interferes with prenatal development at the fourth week.
disrupting formation of facial features, causing structural defects of the heart, and leading
to low IO and learning disabilities. Fortunately, Anika knew all about these effects and
had long since stopped taking the drug. However, the nurse frowns when she sees a
notation for another drug that Anika is currently taking for a skin condition- the
antibiotic doxycycline. This drug can cause tooth discoloration in childhood following
exposure as a fetus.
