Pregancy Calendar: A calendar of each week of pregnancy. What to expect in each trimester.
The first month you are pregnant
The first week of pregnancy
Figuring out your due date is done by working back to the first day of your last
menstrual period. Since it is sometimes difficult to know exactly when
conception occurred, the first day of your last menstrual period is the starting
point for the next nine months. Therefore, the first week of your pregnancy is
actually the week you started your last period. Most pregnancies last
approximately 280 days, or 40 weeks.
The second week of pregnancy:
During the second week, estrogen triggers your uterus (as it has each month
since you started menstruating) to form a lining of tissue. This also raises
levels of the hormone progesterone and prepares the uterus to receive a
fertilized egg. The lining of your uterus gets thicker as the egg prepares to be
released from the end of your ovary into the fallopian tube that leads to your
uterus. The ovaries ripen eggs in fluid-filled sacs called follicles and it is
during this brief period that your body's preparation can result in conception
once sperm meets the egg.
The Third Week of pregancy:
It is during this week that you actually became pregnant (the egg meets the
sperm)! You probably will not know you are pregnant for a few weeks, though some
women swear they know the exact moment they conceived. Around mid-cycle (day 14
of a typical 28-day cycle), you ovulate and one of your eggs is swept into your
Fallopian tube. In the next 12 to 24 hours that egg can be fertilized. After the
egg is fertilized it implants itself in your uterus. Sometimes there is a slight
amount of bleeding when the egg is becoming implanted, but this is perfectly
normal.
Once fertilized, the egg is called a zygote, and immediately closes its outer
membrane to the rest of the sperm that have made it this far. It then begins
dividing into identical cells and will begin the 7 to 10 day journey down the
Fallopian tube to the uterus, where it will continue to grow. Once it has
implanted, the fertilized egg is called a blastocyst.
The baby’s sex is
determined at the time of fertilization and is determined by the type of sperm
that fertilizes the egg. Y-Chromosome bearing sperm will produce a male and
X-Chromosome bearing sperm will produce a female.
