Pregnancy Week by Week Guide – First Trimester

Changes happen so rapidly from week to week throughout pregnancy. The first trimester is definitely an delicate phase of childbearing, with rapid changes happening to both mother and baby. This is the trimester when pregnancy symptoms are in their peak. Although every woman’s pregnancy differs, certain symptoms are felt by most – especially a missed period!

Weeks 1 to 3

Ovulation should take place a little while around the third week, and conception can take place. One in the first pregnancy symptoms could possibly be implantation bleeding, which could happen when the fertilized egg implants itself in to the wall of the uterus. This bleeding must be very light, as well as perhaps pink in color.

Other symptoms that can start might include: nausea, bloating, tender/swollen breasts, not to mention, a missed period. Some symptoms may well not appear until a bit later inside the first trimester. Some symptoms may actually last during the entire entire pregnancy.

Weeks 4 to 7

A home pregnancy test taken around week four or five will demonstrate a good result. A blood test can detect the pregnancy hormone earlier than a home pregnancy test, which can show a good result before the next monthly period is due.

These month or so involve rapid growth with the baby. The cells are rapidly dividing, and the placenta has 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 childbearing, the child’s heart could be heard via an ultrasound. The sex in the baby is set at this point, as either testes or ovaries will build up. The mother’s uterus has become the size of an grapefruit by now! This would be a great week to get a first prenatal appointment.

On week 9 on the pregnancy calendar, the baby’s bones and cartilage start to form. Arms and legs are developing, as are webbed fingers and thumbs.

By week 10, a pregnant woman will most likely learn to ‘show’ as her uterus will continue to enlarge and rise. She will also more than likely commence to experience bleeding gums and nose, due to increased amount of blood flow.

Weeks 11 and 12

The baby is merely about fully developed by the final in the first trimester, although her or she still must grow and strengthen all of the organs and systems. The baby’s heart rhythm is incredibly rapid – beating any where from 140 to 160 beats per minute.

An ultrasound is normally completed now to ascertain if the newborn is growing properly, and to date her pregnancy. Certain prenatal tests might be conducted currently, especially if your mother has ended age of 35. Tests including chronic villus sampling could possibly be done around this time around to detect any chromosomal abnormalities – for example Down Syndrome – or genetic disorders. These tests usually are not mandatory, and can be opted beyond by the mother if she so chooses.

By the end from the 12th week, pregnancy symptoms should be much milder, and should be beginning to subside. There are some unfortunate girls that may go through certain symptoms for months. The threat of miscarriage is drastically reduced by the conclusion from the first trimester, which is why a lot of women elect to wait until now before announcing their pregnancy.
