Cramps and Backache Symptoms in Early Pregnancy

Cardiovascular, Blood Flow and Temperature Changes

You will start detecting pregnancy or notice its symptoms 7 to 10 days after ovulation.
Blood Flow Increase during Early Pregnancy

About six weeks following the last period of a pregnant woman, volume of blood that now flows through her pregnant body will increase gradually.

Pregnancy necessitates remarkable changes in your blood flow. Most obvious of these occurs in your uterus as well as in development of your placenta which enables the fetus to nurture. Blood flow to your skin also increases, thereby making you feel a little warmer and even sweat more, especially in your feet and hands.

This blood flow increase helps to boost the metabolism of your body by almost 20%, which creates extra body heat to protect you from feeling too cold. During pregnancy, your body core temperature will usually rise to around 37.8º Celsius, which is equivalent to around 100.4º Fahrenheit, whereas the normal body temperature is around 37º Celsius, which is equivalent to around 98.6º Fahrenheit. Surplus blood helps your body in meeting the metabolic requirements of your developing fetus, and in flowing to other vital organs, such as your kidneys, etc.

Nipple and Breast Changes

Within a period of 2 to 4 weeks of conception, your breasts will undergo a massive change.

Breast Changes during Pregnancy

Your breasts will begin to enlarge and develop under direct influence of a special hormone in the body, known as oestrogen. This hormone plays the main part during puberty, in the development of your breasts.

Changes noted in your breasts during pregnancy are on account of formation of the growing milk ducts for later breastfeeding purposes. An increase in blood supply will also cause veins of your breasts to become more obvious during pregnancy. As sign of pre-menstruation, some women may undergo breast changes shortly after conception. Accordingly, they may even sense changes prior to the date of their next period.
