The journey of 9 months when you have a life growing inside you is very beautiful. However, it is also important to be extremely careful during this period as now your life and your baby’s life are interdependent on each other.
When you visit the OB-GYN for the very first time, he or she will give you the tentative due date. This pregnancy calculator uses this due date to mark the important weeks of your pregnancy, which starts from conception and ends at giving birth.
Various Phases of Pregnancy
The 9-month period of pregnancy is divided into 3 trimesters, each trimester consisting of 12 weeks. Every trimester has certain important milestones, like the time when the baby’s heartbeat can be heard or when the baby starts kicking in your womb.
Trimester 1
Pregnancy actually doesn’t begin from conception. In fact, it is on the 3rd week of pregnancy when you actually conceive the baby. By the 4th week, you’ll know that you’re pregnant.
Once you conceive the baby, the first sign of life is discovered when you can hear its heartbeat.
So, following are the important milestones of Trimester 1:
Week 3: Conception
Week 4: Pregnancy Detection
Week 6 – Week 7: Heart beat detection by ultrasound
Tips to take care of yourself during this phase:
- Regular light exercise
- Drinking plenty of water
- Diet rich in: prenatal vitamins, low-fat form of protein, fibre, 300 calories, vegetables and fruits
- Say no to: Drugs, alcohol, caffeine, smoking, raw or smoked seafood, sushi, mercury-rich foods, raw sprouts, deli meat, hot dogs, pineapple, papaya and unpasteurized milk
Trimester 2
The first trimester is a delicate stage because the baby is still in foetus form, even though you can hear its heart beat. By the time you reach the second trimester, it grows a bit more. Thus, the risk of miscarriage reduces.
In this phase, its body will start developing rapidly week by week. It can start hearing sounds and kick inside your womb. The doctor can tell its gender too, though it is not legal in all countries to find out the gender of the baby before birth.
Following are the important milestones of this trimester:
Week 13: Your risk of miscarriage reduces
Week 18 – Week 21: First kick, able to hear sound and detection of gender is possible
Week 23: The baby is now premature
You continue following the daily care routine you followed in the first trimester. Additionally, you also need to ensure that you keep your teeth and gums healthy now. Else, it may lead to premature labour, which is risky for your baby’s health.
Trimester 3
The final phase is when birth is really close. That’s when your womb reaches its full size and the baby is literally living inside you. Now, it is breathing and getting nourished, ready to come out into the world any moment.
There are 2 main milestones here:
Week 28: Your baby takes its first breath
Week 38 – Week 42: Period of birth
This is a crucial period when you may feel pain or swelling. However, you need to remain active or walk a lot. At the same time, you also need to rest a lot. Avoid going on long drives as well as air travel.
