6 Weeks Pregnant: The 6th Week of Pregnancy
Congratulations! Weeks four through seven are when most women discover they are pregnant. This week-by-week newsletter will keep you informed about what to expect for you and your developing baby during your pregnancy. If you have just found out that you are pregnant, you may want to begin by reading the previous articles.
Pregnancy Week 6: How is pregnancy calculated?
There is always a lot of confusion when discussing the way in which pregnancy is calculated. Since most women do not know when they conceived, pregnancy is always determined from the first day of your last menstrual period (LMP). Given that this is the way pregnancy is calculated, your pregnancy will last around 40 weeks. For more information on how pregnancy is measured, please see our information on calculating your dates.
Pregnancy Week 6: What changes are occurring with your body?
You may notice that you have gained a few pounds, while other pregnant women may have actually lost weight. You may begin noticing changes in your breasts including tenderness, darkening of the areola, and swelling. You may also begin experiencing heartburn, which is a common complaint during pregnancy.
Some women experience bleeding during pregnancy that may not be a sign of any problem. This spotting (finding spots of blood in your underwear or on toilet paper after using the restroom) may be accompanied by light cramping. You would want to consult with your health care provider if the bleeding becomes heavy like a normal period or if the cramps are worse than normal period cramps. This could be a sign of a miscarriage.*
Pregnancy Week 6: What is happening with your baby?
The formations of the lungs, jaw, nose, and palate have begun. The hand and feet buds have webbed-like structures that will become the fingers and toes. The brain is continuing to form into its complex parts. A vaginal ultrasound could detect an audible heartbeat at this time.*
Pregnancy Week 6: How big is your baby?
Your baby is about ¾ of an inch (19.05 millimeters) in length.*
What should you plan for this week?
Knowing your blood type and your partner’s blood type is important during pregnancy.
Each person’s blood is one of four major types:
- Type A
- Type B
- Type AB
- Type O
Blood types are determined by the types of antigens on the blood cells. Antigens are proteins on the surface of blood cells that can cause a response from the immune system. The Rh factor is a type of protein on the surface of red blood cells. Most people who have the Rh factor are Rh-positive. Those who do not have the Rh factor are Rh-negative.
Pregnancy Week 6: Tips for making your pregnancy better
Some women complain that their prenatal vitamins make them sick to their stomachs. If this is happening to you, then you may want to take them with food or take them at night before going to bed. If you continue to have problems tolerating your prenatal vitamins, consult your health care provider before stopping them completely.
