So, you’re 4 weeks pregnant. This is when you may first start to suspect you are pregnant… perhaps that’s because your period hasn’t arrived! You may start to experience some symptoms of early pregnancy.
At 4 weeks pregnant, your egg is now well attached to the inside wall of your uterus. It’s sending out tiny little hair-like tendrils, which will wrap around the abundant small blood vessels in the lining of your uterus. This helps to provide oxygen and nutrients to your growing baby.
In normal circumstances, your blood and the blood of your baby do not mix. You both have a separate circulatory system. Exchange of oxygen, nutrients and waste products is made possible due to the closeness of your blood vessels to the blood vessels of the placenta.
Implantation bleeding may occur for some women, resulting in some spotting at around about 10 – 14 days after conception. Some women may think they are starting to get their period, however implantation bleeding is very light and lasts only a day or two.
If you have an indoor cat, you may be wondering about toxoplasmosis — or perhaps you’ve not yet heard of it. It’s best to have your partner to change the kitty litter while pregnant due to a parasite which is found in some cats’ faeces.

4 Weeks Pregnant – Your Baby
At 4 weeks pregnant, your baby is now classed as an ‘embryo’, and it’s heart and a primitive circulatory system rapidly form. Your baby’s neural tube begins to form. The neural tube will develop into the nervous system, consisting of the brain, spinal cord, hair and skin. This is a good reason to up your dietary intake of folate (known as folic acid in synthetic form), which is found in most pregnancy supplements and a range of foods. It helps the neural tube develop and prevents a major birth defect, spina bifida, from occurring by around 70%.
It’s important to note that 1 in 4 people will have problems converting synthetic folate. A MTHFR gene mutation affects 1 in 4 people seriously and 1 in 2 mildly. One form of the mutation results in a 40% to 60% decreased ability to produce the body’s most active form of folate. The best supplement to take instead of folate is folinic acid, especially if you’ve had problems with fertility, pregnancy complications or miscarriage. A simple test for MTHFR may give you some answers, so don’t hesitate to ask your doctor.
