1 Week Pregnant – Mother’s Progress

When you are 1 week pregnant, you won’t be aware of any immediate changes to your body, however, there is an awful lot of change going on, not only to your implanted embryo, but to you too, even long before the pregnancy symptoms begin. From the moment fertilization takes place your body triggers a sequence of events that begin to prepare itself for the next nine months of gestation.

1 Week Pregnant

Virtually every organ in your body needs to adapt itself to cope with the increasing demands that your pregnancy will place upon it. All organ tissue is going to now increase in size and activity therefore your metabolic rate will rise by up to 25% to allow sufficient oxygen to circulate. In order to achieve this your heart rate will increase by up to 40% within the first 20 weeks and this all begins from the very moment of conception.

This increased blood supply will go to your uterus, cervix, vulva, kidneys and breasts with the tissues taking on blue/purple color. This purple color is the distinct mark of pregnancy and in the now outdated medical procedures, was the way doctors used to confirm the pregnancy after performing an internal examination.

To ensure the sustainability of your pregnancy and that no area of your body is deprived of blood, your total blood volume throughout your body needs to increase as well from the usual 5 litres (8.5 pints) to around 7-8 litres (12-14 pints) which will begin now in these pregnancy first stages and continue on gradually throughout term.

Some women are so sensitive to these early changes in their bodies that they will have an idea that they may already be into their first week of pregnancy before they even miss their period. This blood increase to your body, along with the sudden surge of estrogen is what gives your breasts that tingling sensation.

These sudden changes can also cause increased feelings of tiredness and being overemotional, even in these early days, although this may not seem apparent to many just yet as they could also be confused with the usual associated feelings of being premenstrual, except this month the surge of hormones flooding your body are for very different reasons as you are soon to discover.

These pregnancy hormones consist of progesterone, which relaxes the muscles of your uterus to prevent you from expelling the embryo and the hCG hormone which sustains the pregnancy throughout. HCG happens to also be the same hormone that is detected in elevated amounts when performing a urine or blood test for pregnancy.
