Different Stages of Pregnancy - First Trimester: Weeks 1-12

Weeks 1-4: Conception and Implantation

Here your journey to become parents begins. It is the time where the sperm has finally fertilized the egg and the zygote has formed. The egg will finally travel to the fallopian tube and implants to the uterine lining. You don't really realize if you are pregnant or not but you might see some early signs that include cramping, missed periods and spotting which is often known as implantation bleeding. A pregnancy calculator will become handy to track your pregnancy week by week.

Weeks 5-8: Embryonic Development

Weeks 9-12: Forming Vital Organs

At this stage, your embryo is now a fetus. Most of the major organs such as heart lungs and brain start to form and your fetus will begin to move. The fetus is at the moment too small for the mother to feel the movements. Pregnant women may notice a change in their skin and hair and maybe a tiny baby bump is there to make an appearance too.

Second Trimester: Weeks 13-26

Weeks 13-16: Growing Rapidly

The second trimester is often considered the most comfortable period for pregnant women. Morning sickness typically subsides, and energy levels may improve. The fetus grows rapidly, and its facial features become more distinct. By week 16, some women may start to feel fluttering movements known as “quickening.”

Second trimester is often called the honeymoon stage, most of the exhausting symptoms like nausea and morning sickness subside and you slowly get your energy back.

By 5th month or at 16th week you may notice movements as well and that is one of the most exciting parts of your pregnancy journey.

Weeks 17-20: Gender Reveal and Increased Movement

At this stage, your little baby is gaining muscle and fat and the movement will become intense too. It is also the time to get to know the gender and reveal it to the family or maybe throw a gender reveal party. Before getting to know the gender yourself, people start guessing it as well with the symptoms you are getting. SOme people believe that if you are craving sweets then it's a baby girl and if the cravings are salty, it's a baby boy. However, these "baby boy symptoms" are mostly old wives' tales and not scientifically proven.

Weeks 21-24: Developing Senses

At this stage, your baby is able to hear the sound from outside and maybe respond to voices and music. Mothers usually feel intense kicks and movements and at this stage the mother should maintain a healthy diet and keep herself super hydrated for the baby's development.

Weeks 25-26: Gaining Weight

The fetus continues to gain weight and grow in length. Its skin starts to smooth out as fat accumulates. Pregnant women may experience backaches, leg cramps, and swelling in the ankles and feet due to increased weight and pressure on the lower body. Using a pregnancy weeks guide can help manage and understand these changes.
