As women stroke their round bellies and ponder the mystery unfolding inside them, and as their partners feel that first ripple of life under their curious fingertips, it is natural to wonder how their baby is changing throughout the pregnancy week by week. Then there are the physical symptoms – the nausea and tiredness, the calves that cramp in the night, and the breasts that have never been so LARGE. Women often wonder if the amazing changes they are experiencing are normal, and when they should seek help.
As if pregnancy symptoms aren’t enough to cope with, there are all the appointments and tests, and trying to remember when to see who, about what, and how often? To help you understand and contend with what is happening during your pregnancy week by week, we've put together a guide to the three trimesters of pregnancy. It explains how your baby is developing, what symptoms you may experience and the tests and appointments that may be needed.
Pregnancy Week by Week Articles
3 Weeks Pregnant
"It’s time to sound the drum roll. Your 3 weeks pregnant. This is the week your baby is conceived! If you have been trying to conceive you will have earmarked the magic four days this week which will give you your best chance of success. You have made love on some (or maybe all!) of those days… so when is the magic moment?" This article by Yvette Barton gives in depth information on the third week of pregnancy.
2 Weeks Pregnant
"Even though we say ‘2 weeks pregnant’ you are still not actually pregnant yet. As we explained in 1 Week Pregnant, if you receive a positive pregnancy test the first day of your last period is the best constant upon which an Estimated Due Date or EDD can be calculated. However while you may not be pregnant yet your body is not hanging around idly waiting for a pregnancy to occur. Quite the contrary. Your body is working hard to prepare your body for a baby."
1 Week Pregnant
"Even though we say ‘1 week pregnant’ the truth is that you are not actually pregnant yet. It is hard to tell when ovulation occurs, so the first day of your last period is recorded as the beginning of your pregnancy and is the day that your Estimated Due Date (EDD) is calculated from. For this reason if you are pregnant, the start of your menstrual cycle will be regarded as 1 week pregnant." This article by Yvette Barton gives detailed information on the first week of pregnancy.
From Bump to Buzz
This is a wonderful YouTube video featuring time lapse pregnancy photos from the start of pregnancy right the way until the baby is born. The photos are accompanied in the video by a lovely song called "Something New" written by the lead singer from boy band McFly - Tom Fletcher (the father of the baby). The end result is very charming.
Nine Months of Pregnancy
Perhaps you have just discovered you are pregnant, you are hoping to be, or your partner has just given you the news. This article gives a brief snapshot of what nine months of pregnancy holds in store.
The First Trimester - Weeks 1 to 14
By the end of the first trimester of pregnancy (14 weeks) the risk of malformations and miscarriages diminishes significantly. The baby will weigh around 45gms and be around 8cm long. They float comfortably in a pool of warm liquor.
The Second Trimester- Weeks 15 to 28
The second trimester is a period of rapid growth for your baby. By 18 weeks of pregnancy the baby will weigh around 200gms and be approximately 14cm long.
The Third Trimester- Weeks 29 to Birth
In the third trimester of pregnancy the baby increasingly matures as well as gains weight. At 34 weeks of pregnancy the baby weighs around 2 kilograms and their chances of survival are very good. At 38 weeks of pregnancy the baby will be around 45-55cm long and around 3000-4000gms.
