The fifth week of pregnancy is when most women realize they may be pregnant. This is the first week after your missed period.


You are probably beginning to experience the pregnancy symptoms such as breast tenderness, fatigue, nausea or morning sickness.

Remember that this is a crucial time in your life, and if you haven’t stopped your bad habits or changed your lifestyle, now is the time to do so.

These early months of pregnancy are essential for your baby’s development. Taking a few key steps now can help protect your baby’s health and your own.

Get early prenatal care and keep up with your appointments. Good prenatal care is essential to your baby’s health and to yours. It is time to choose a doctor or midwife and schedule your first appointment.

Take your prenatal vitamin. Most prenatal supplements contain more folic acid, iron, and calcium than you’ll find in a standard multivitamin. Pregnant women need more of these nutrients.

It’s vital to get enough folic acid while trying to conceive and during your first trimester because it greatly reduces your baby’s risk of developing neural tube birth defects such as spina bifida.

Consult your healthcare provider about the medications you’re taking.

Stop smoking. Smoking increases your risk of a host of problems, including miscarriage, placental problems, and preterm birth. It also slows fetal growth and increases the risk of stillbirth and infant death.

Stop drinking alcohol. As little as one drink a day can increase the odds of low birth weight and raise your child’s risk for problems with learning, speech, attention span, language, and hyperactivity.


Baby’s development:

Deep in your uterus your embryo is growing at a furious pace. At this point, he’s about the size of a sesame seed. He is now made up of three layers of cells, the ectoderm, the mesoderm, and the endoderm, which will later form all of his organs and tissues.

During this week, your baby’s vital organs are growing; the heart, central nervous system, bones and muscles are forming quickly from this point on and the skeleton begins to take shape.

Furthermore, your baby’s heart is developing quickly. Beginning as a simple tube, it begins to separate into four chambers and starts pumping blood.
Some ultrasounds will be able to pick up on the heartbeat as early as five weeks.

Your baby already has some of its own blood vessels and blood begins to circulate.


A string of these blood vessels connects your baby to you and will become the umbilical cord.
