Obstetricians have standardized timing a pregnancy to 40 weeks so that it is easier to communicate and determine due dates as well as testing. The first day of your last menstrual period is used to calculate your due date. 20 weeks is exactly half way through your pregnancy or about 4 1/2 months along.

CDC advises women who are pregnant or likely to become pregnant to not travel to areas with malaria risk, if possible. Malaria in pregnant women can be more severe than in women who are not pregnant. Malaria can increase the risk for serious pregnancy outcomes, including prematurity, miscarriage, and stillbirth. If travel to a malarious area cannot be postponed, use of an effective chemoprophylaxis regimen is essential. However, no preventive drugs are completely effective.

Yes. It is recommended that pregnant women take special care of their teeth and gums during pregnancy and have their teeth cleaned and checked by a dentist at least once when pregnant. Tell the dentist you are pregnant. Your dentist and medical doctor can determine if any special procedures, other than routine cleaning, should be postponed until after pregnancy.

You can sleep on your back in early pregnancy or until you feel comfortable to do so. As the pregnancy advances you may experience a sense of faintness if you lie on your back. This is called supine hypotension. It is caused by the weight of your uterus and your baby pressing on the major blood vessels. This can be alleviated by the number of pillows you use. If you need to sleep on your side then the left side is best because it can help increase blood flow to the placenta.

It is important to remember that it can take a normal, healthy couple many months to become pregnant. There are many factors that affect your ability to become pregnant even if you have been able to have intercourse during your most fertile time. If after several months you have no success, consult your healthcare provider. Since you have been monitoring your cycle with the LUNA, you will be able to give your healthcare provider a clear picture of your fertility cycle.

Apparently not. It seems that the amount of tissue you grow decreases with each "cycle." Brava service representatives are telling us 40-50cc for the second cycle (this may be more than 10 weeks, see above).

To reduce load time on the classified ads pages, we'll be getting rid of the full size pictures that some advertisers include with their ads.

We've left this question until last because it's probably the one we get asked most often. The answer we give is always the same: I haven't the foggiest idea ? and nor has anyone else. Thousands of analysts and journalists make a good living satisfying people's insatiable desire to read the future. Unfortunately, almost all of them are useless. The forecasting record of economists and analysts, even for such clearly defined targets as future interest rates or inflation rates, is very poor.

This is a pretty confusing issue for a lot of pregnant women. The fact is when you're in your 5th week of pregnancy, you are 4 weeks pregnant! During the week you start your period, you are in your first week of pregnancy, but you have not yet completed any weeks so you are zero weeks pregnant. Think about it this way - you don't say that a baby is one year old during his first year of life do you? He is not considered to be one year old until he's actually in his second year.

During pregnancy expect to increase about a cup size and a rib size, so from a 34A to 36B. The underwired bras can be uncomfortable in pregnancy while the breasts are tender. The soft-cup style are more comfortable and may have enough give to span two sizes. If you are buying bras for breast feeding it is important to shop for this during your last month when you will be close to the size you will be after your baby is born.

Technically yes. However, there is a delayed implantation of the embryo: the fertilized egg divides a few times and then just floats in the uterus. This allows the mother, who has lost over a third of her body weight feeding her recently delivered baby and herself with metabolized blubber, to regains some of that weight before the new fetus begins to grow. After three to four months, the blastocyst attaches to the uterine wall and begins growing again.

Pregnancy in the fallopian tube (ectopic pregnancy). You should have an urgent ultrasound to see if it is an intrauterine viable pregnancy and then you should take complete bed rest and folic acid tablets.
