Pregnancy: First Trimester

What is changing for baby

Did you know that you are actually not pregnant the first two weeks of your ‘pregnancy’?

Indeed pregnancy is calculated from the first day of your last periods and is then divided into trimester (1 to 12, 13 to 27, and 28 to birth).

By the time ovulation and fertilisation occur, you are already at the end of week 2.

The fertilised egg then grows into a microscopic ball of cells called blastocyst, which implants on the wall of your uterus. This implantation triggers a series of hormonal and physical changes in your body (see my previous blog: first trimester of pregnancy: what is happening to the mum-to-be?)

We call week 3 to week 8 the embryonic phase during which the embryo develops major organs. Although the majority of women would not be aware of their pregnancy by then, it is important to note that the embryo is vulnerable to toxic substances such as alcohol, infection or radiation during that stage.

Did you know that the heart of your future baby start beating on week 3  + 1 day after fertilization?

By week 9 the embryo changes to a fetus status as it matures. By now it measures 2.5 cm (1 inch)!

By week 11 your uterus will have changed from the size of a fist to the size of a grapefruit!

Is Osteopathy safe during Pregnancy?

Osteopaths are highly skilled and undergo a minimum of 4 years training. Gentle osteopathic techniques are perfectly safe at all stages of pregnancy. The cranial osteopathic approach is a particularly gentle way of working with the body’s own natural mechanism for releasing and re-balancing tensions, without force.
