You might notice that symptoms like nausea and fatigue are going away. But other new, more noticeable changes to your body are now happening.
Your abdomen will expand as the baby continues to grow. And before this trimester is over, you will feel your baby beginning to move! Some of the same discomforts you had in your second trimester will continue. Plus, many women find breathing difficult and notice they have to go to the bathroom even more often. This is because the baby is getting bigger and it is putting more pressure on your organs. As you near your due date, your cervix becomes thinner and softer called effacing.
This is a normal, natural process that helps the birth canal to open during the birthing process. Your doctor will check your progress with a vaginal exam as you near your due date. Get excited — the final countdown has begun! The medical term for the due date is estimated date of confinement EDC. However, only about four per cent of women actually give birth on their EDC.
Here is a simple breakdown of approximately how pregnancy weeks and months are counted and divided in the 3 trimesters —. The total number of weeks a female is in her pregnancy is a little different from how many weeks pregnant she actually is. If a female is 16th week of pregnancy, she is actually or maybe 15 weeks and some days pregnant. This is because doctors calculate the pregnancy weeks from the last period of the female, not from the day or week she possibly conceived. So, your doctor may say you are in week 16 while you are actually 15 weeks pregnant.
Most females rely on the doctor to find out their pregnancy due date. But you can actually calculate it yourself. That will give you your due date. To be completely sure, double-check it with your doctor! Email address:. If you're carrying a single baby, a full-term pregnancy is between the start of 39 weeks up to the end of 40 weeks. If you're carrying twins, a full-term pregnancy is considered at least 38 weeks.
Which is right? Short answer: both. Turns out how many weeks into pregnancy you are is a little different than how many weeks pregnant you are. Fifteen full weeks have gone by, but not 16 weeks, so people say that you're both 15 weeks pregnant and in week 16 of pregnancy. To clear things up, think about birthdays. When you turned 1 year old, you had lived through your first year and were starting on your second.
In other words, on your first birthday you were in day one of your second year. But no one said you were 2 years old until you'd finished that second year and had begun your third. So try to remember the first day of your LMP and add 40 weeks to that.
Why start the clock on pregnancy before sperm even meets egg and, actually, before your ovary even dropped the fated egg that made your baby? The LMP is simply a more reliable day to date a pregnancy from.
