Fetal Development (First Trimester)

Surprise, surprise! Really you're not pregnant the first or second week! Crazy huh?!

Conception typically occurs 2 weeks after your last period. Calculating your due date, the health provider will count ahead 40 weeks from the start of your last period.

During week 3, the sperm and the egg will unite in one of your fallopian tubes and become one called zygote. The zygote has 46 chromosomes; 23 from you and 23 from the dad. These determines what the sex of the baby & traits the baby has like their eyes, hair
color, hair skin and maybe intelligent/personality.

By week 4, the zygote will be in the uterus, it's now known as a blastocyst. A blastocyst separates into 2 sections. The inner group will become the embryo, the outer group will become the cells that nourish and protect it. The blastocyst will bury it into the uterine wall for nourishment. This is called implantation. The placenta- nourish your baby throughout pregnancy will also start to form.

During week 5 and 6, the baby's brain and organs start form. Basic features will be appearing and buds will be the baby's arms and feet.

In week 7 & 8, the baby's head and face features will start forming and be visible. The trunk of the baby's body will start to straighten and the baby will be around 1/2 inches.

During week 9 & 10, the baby's neck and toes are forming and the eyes/ears are continuing to develop. Also the baby has grown bones and can bend their elbows.

In week 11 & 12, the baby is now a fetus and is developing genetials and fingernails. It's now about 2 1/2 inches and weighs about 1/2 oz.

First Trimester; What's going on with me


Pregnancy might leave you feeling delighted, anxious, exhilarated, and exhausted. Sometimes all at the same time! You might also experience misgivings, weeps and mood swings. Of course naturally as a mom you'll worry about your baby's health!


The physical changes during the first trimester,

  • You'll have bouts of nausea. It can strike during any time of the day; eating small amounts of meals throughout the day can help.
  • You'll also have swollen breasts, wearing a supportive bra or sports bra might help. You'll also have an increase in urinating, especially during the night.
  • Fatigue also ranks high among first trimester symptoms. During early pregnancy, levels of the hormone progesterone soar, which can put you to sleep. At the same time, lower blood sugar levels, lower blood pressure and increased blood production might team up to sap your energy. To combat fatigue, rest as much as you can. Make sure you're getting enough iron and protein. Include physical activity, such as a brisk walk, in your daily routine.
  • You might have food cravings, and foods you may not like, it's common.
  • Pregnancy causes your blood vessels to dilate and your blood pressure to drop, which might leave you lightheaded or dizzy. When you're lightheaded or dizzy, rise slowly after lying or sitting down. If you start to feel dizzy while you're driving, pull over. If you're standing when dizziness hits, sit or lie down.
  • During first trimester pregnancy, the movements that push swallowed food from your esophagus into your stomach are slower. Your stomach also takes longer to empty. This slowdown gives nutrients more time to be absorbed into your bloodstream and reach your baby. Unfortunately, it can also lead to heartburn and constipation. To help, eat small meals throughout the day, avoid fried foods, carbonated drinks, citrus fruits or juices, and spicy foods.

Fetal Development (Second trimester)

During week 13 & 14, your baby's intestines have returned to his or her abdomen from the umbilical cord, where they've been growing for the past couple of weeks. Your baby is also beginning to form urine and discharge it into the amniotic fluid. Tissue that will become bone is also developing around your baby's head and within his or her arms and legs. Your baby's arms have almost reached the final relative lengths they'll be at birth and your baby's neck has become more defined. Red blood cells are forming in your baby's spleen.

In week 19 & 20, a greasy, cheese-like coating called vernix caseosa begins to cover your baby. The vernix caseosa helps protect your baby's delicate skin from abrasions, chapping and hardening that can result from exposure to amniotic fluid. For the girls, the vaginial might start to form during these week. You will also start to feel the baby's movements.

During week 21 & 22, your baby is poised to gain more weight. By this week your baby is becoming more active and is able to swallow. Your baby is completely covered with a fine, down-like hair called lanugo. The lanugo helps hold the vernix caseosa on the skin. Your baby's eyebrows might be visible. Your baby right now would be about 7 1/2 inches and weighs around 1lb.

Second Trimester; What's going on with me?

  • You'll also have nasal and gum problems; so switching to a softer toothbrush can help decrease the irritations.
  • You might experience occasional dizziness. If you're having problems with dizziness, drink plenty of fluids, rise up slowly after sitting or laying; you can also lie on your left side to restore your blood pressure.
  • Leg cramps are common as pregnancy progresses, usually happening at night. To prevent leg cramps, stretch your calf muscles before bed, drink lots of fluids, stay physically active; also a hot shower, warm bath or ice massage may help.
  • Your lungs are processing more air than they did before pregnancy, so this might leave you feeling short of breath.
  • You might notice vaginal discharge, so you might want to wear panty liners for comfort.

During the second trimester, you might feel less tired and more up to the challenge of preparing a home for the baby.

Some women may feel heightened sexuality during pregnancy, others feel unattractive, you're struggling with your body image, sharing concerns with your partner. On top of everything else, you might worry about labor, delivery, and motherhood.

Advice for soon-to-be Fathers

After the initial excitement of discovering that you're going to be a father, you may find yourself feeling a little aimless while your partner is pregnant or even after she gives birth. It's a bit lonely. Expectant fathers go through profound changes too, even though their bodies don't change, overcoming fears and assumptions are part of becoming a father. So the most important thing is to stay connected. Have an honest and open relationship with your wife. Also to get involved, for example you should accompanying your wife to doctor appointments even though you might feel a little awkward. Go out and buy some clothes, cribs, toys for the expecting baby. The sooner you get involve, the more involve you are as a parent. You should also deal with your boss, taking some time off while your partner is in labor. That doesn't mean go to your boss office and say "My wife is in labor, and I won't be back for three months." You can take some time off and work a couple days a week. The challenge of being a dad requires giving up yourself and giving it to your child, so take turns taking care of the child. Newly parents often think about things they never expect to think about, the childcare, the neighborhood, the education system. They don't want their child to grow up in a world they did, so they try to give them better chance in the world. Finding support is difficult for men. They tend to be shy going to organizations learning about being expectant fathers. Although everyone is intimidated by the role of the father, don't think that fatherhood is all good, there's bad times too. So don't be surprise when you're enraged by your baby's frequent awakening at nights. The place to get the best support is from your partner. Talk to her about things that frighten or concern you; you guys can come up with a solution. Sometimes there might not be a solution to the problem but feeling understood makes things everything easier.
