What to Expect in the First Trimester of Pregnancy – Pregnancy Week-by-Week

ADVERTISING

The first trimester of pregnancy is defined by a transformation that is invisible, yet, it is still amazing. Understanding what physical and emotional changes to expect during the first trimester will help you comfortably face up to the months ahead. 

A woman’s body undergoes many changes during the first trimester. The body releases hormones that have an effect on almost every organ in the body.

A pregnancy lacks the first indication that you might be pregnant. Here’s your week-to-week guide in knowing and identifying the changes in your first trimester.

Week 1 – Week 2

At this stage, technically, you are not yet pregnant, because doctors measure your due date from the first day of your last period. You will feel the usual signs of your menstruation: vomiting, cramping, sore breasts, mood swings, etc. 

Ovulation takes place during week two. Ovulation signs include lower abdominal pain towing, tenderness of the breast, oily discharge that resembles egg whites, and elevated basal body temperature.

Week 3 – Week 4

The fertilized egg implants within the uterine lining during week three. Some women experience moderate abdominal cramping or light spot known as “implantation bleeding”. 

If you have extreme bleeding or serious pain, call your doctor. This could signify an ectopic pregnancy where the embryo implants outside the uterus (usually in the Fallopian tube). 

Week 5 – Week 6

During the fifth week, hormone-induced mood swings carry a barrage of feelings. For no conceivable reason, your emotions will change from happy to depressed to angry. 

Other early signs and symptoms of pregnancy — such as tiredness and tenderness to the breast — have also likely stuck around. Week six brings with it one of the most dreaded symptoms for some women: morning sickness (although it may start earlier in your pregnancy). 

Your heightened sense of smell will further intensify this queasiness, setting the stage for cravings and aversions to food. Morning sickness could stick around until the second trimester, so finding ways to cope is best.

Week 7 – Week 8

Other early pregnancy symptoms include frequent urination. Plan your next trip to the movie theatre for plenty of bathroom breaks! 

Your symptoms of pregnancy may have appeared now in full force: nausea, tenderness of the breast, fatigue, frequent urination, swings of mood, bloating, and others.  

Another odd symptom in your mouth is extra saliva, which often lasts until the end of the first trimester. Many may often suffer headaches due to hormonal spikes, along with loss of caffeine, fatigue, and dehydration.

Week 9 – Week 10

In addition to nausea, which accompanies morning sickness, many women suffer from constipation and excess gas. Don’t worry though, after the first trimester, all of these gastrointestinal signs pass. 

In the first trimester, women have the radiant “pregnancy glow”, while others suffer from hormone-induced acne. You will also notice your breasts, and your belly grow bigger every week.

Week 11 – Week 12

Your baby bump could cause pain and cramp around your abdomen. The discomfort in the round ligament can be slightly irritating or cringingly painful. One side effect is clear veins on the skin, which are particularly noticeable in women with fair skin.

Week 13

When you reach the end of the first trimester, several signs of early pregnancy lessen. However, you might notice you’re feeling dizzy all day long. 

You may thank these dizzy spells for hormonal swings, decreased blood flow, and lower blood pressure. Combat them by taking deep breaths with your head between your knees.

Major Changes with Your Emotions

Pregnancy could leave you feeling relaxed, nervous, exhilarated, and exhausted — sometimes, all at once. Even if you are excited to be pregnant, a new baby adds to your life emotional tension. 

It’s natural to be worried about the health of your infant, your parenting transition, and the financial demands of raising a child. If you live, you may be worried about how to balance family and job demands. 

You may be having mood swings as well. Take care of yourself, and look for understanding and encouragement towards your loved ones. If changes in your mood get severe or intense, consult with your health care provider.

Conclusion

Your healthcare professional will treat, enlighten, and reassure you throughout your pregnancy, whether you choose a family doctor, obstetrician, nurse-midwife, or other pregnancy specialists. 

Your first appointment will concentrate on assessing your general health, recognizing any risk factors, and deciding the gestational age for your baby. Your health care professional will ask specific questions about the past of your health. Make sure to be honest.
