Changes come about so rapidly based on data from week to week throughout pregnancy. The first and foremost trimester is a very delicate evolution of pregnancy, investing in rapid fluctuations happening to both mother and baby. This is the trimester when pregnancy symptoms are at such a peak. Although most any woman’s pregnancy is different, little symptoms are felt by most – especially a missed period! Weeks 1 to 3 The first two weeks of pregnancy do not actually involve a fetus. A baby is actually conceived sometime around the third week.

A pregnancy is counted from day 1 of a woman’s last menstrual period for dating purposes, however, no baby actually exists until week 3! Ovulation should occur sometime around the third week, after which conception can take place. One of the first pregnancy symptoms may be implantation bleeding, which can happen when the fertilized egg implants itself into the wall of the uterus. This bleeding should be very light and perhaps pink in color.
Other symptoms that can start may include: nausea, bloating, tender/swollen breasts, and of course, a missed period. Some symptoms may not appear until a little later in the first trimester. Some symptoms may actually last throughout the entire pregnancy. Weeks 4 to 7 A home pregnancy test taken around week 4 or 5 will show a positive result.
A blood test can detect the pregnancy hormone earlier than a home pregnancy test, which can show a positive result even before the next menstrual period is due. These few weeks involve the rapid growth of the baby. The cells are rapidly dividing, and the placenta is being formed. The baby’s heart actually starts beating around week 6 or 7. The eyes and umbilical cord are also underway.
Weeks 8 to 10 By week 8 of pregnancy, the baby’s heart can be heard through an ultrasound. The sex of the baby is determined at this point, as either testes or ovaries will develop. The mother’s uterus is probably the size of a grapefruit by now! This would be a good week for a first prenatal appointment. On week 9 on a pregnancy calendar, the baby’s bones and cartilage begin to form. Arms and legs are developing, as are webbed fingers and thumbs. By week 10, a pregnant woman will probably start to ‘show’ as her uterus continues to enlarge and rise.
She will also most likely begin to experience bleeding gums and nose, due to the increased volume of blood flow. The baby’s tail should have disappeared by now, and he or she will begin moving around in the mother’s womb. Weeks 11 and 12 The baby is just about fully developed by the end of the first trimester, although she or she still needs to grow and strengthen all the organs and systems. The baby’s heartbeat is very rapid – beating anywhere from 140 to 160 beats per minute. An ultrasound is usually carried out at this point to determine if the baby is growing properly and to date the pregnancy.
Certain prenatal tests may be conducted at this time, especially if the mother is over the age of 35. Tests such as chorionic villus sampling may be done around this time to detect any chromosomal abnormalities – such as Down Syndrome – or genetic disorders. These tests are not mandatory and can be opted out of by the mother if she so chooses. By the end of the 12th week, pregnancy symptoms should be much milder and should be starting to subside.

There are some unfortunate women who may experience certain symptoms for months. The threat of miscarriage is drastically reduced by the end of the first trimester, which is why many women choose to wait until this time before announcing their pregnancy. Start raising a family!
