Initial Trimester involving Carrying a child.
Among the biggest life altering moments is when you first discover that you will be pregnant and you begin your first trimester. What precisely is a trimester when it comes to pregnancy stages? Simply the 9 months of pregnancy are divided into three equal parts and the initial trimester is the initial 13 weeks.
What happened to pregnancy week 1 and week 2? Even with the advancements in modern medicine, the precise moment that you conceived can't be accurately pinpointed. When you have had a pregnancy test to confirm that you will be indeed pregnant, the due date is likely to be calculated from the initial day of your last period and although you've not actually conceived it is still counted within the 9 month gestation period. Even though the first trimester is 13 weeks you will only be pregnant for around 11 of those.
Only around 5% of babies are born on their actual due date and that is exactly why you often hear people saying, "My baby was 2 weeks early or 2 weeks late ".The fact is that many babies are born just a few days either side of the actual due date, we only don't have the technology to know exactly when conception took place.
As soon as you really conceive to the end of your 1st trimester your body and baby will undergo some amazing changes, not these is likely to be pleasant for you. Although you will not notice much in the way of outer physical changes during the initial trimester, the developments that are getting on as part of your womb are miraculous.
From enough time that you feel pregnant, your body increases production of progesterone, which prevents your body form shedding your uterus lining. This increased amount of progesterone will stop around 6 weeks once the placenta is developed enough. Pregnancy symptoms like tingling and tenderness of the breasts are due to the high quantities of progesterone that are produced during the first stages of the initial trimester.
Progesterone, also accountable for the extra fat that is connected with pregnancy, really helps to relax parts of your muscles to prevent premature labour and allows your child to "eat" from glycogen deposits; however it is also the key reason for constipation, indigestion and nausea. Your defense mechanisms will become suppressed to ensure your body doesn't expel the infant thinking it is a foreign object and so you will be more prone to catch a cold or some other bug that is flying around.
