Because a pregnancy is counted from the first day of the last menstrual period, but the actual conception doesn't take place til about the 14th day after the start of the last period. So while you're physically 5 weeks pregnant, the medical field considers you 7 weeks pregnant. It's for accuracy of dating.

Determining pregnancy start dates has a bit of guess work involved. At seven weeks I wouldn't be overly concerned unless you are a heavy smoker/drinker, which could easily show as slowing the growth process of the baby. Talk to your doctor!

If someone has an ultrasound and it indicates 7 weeks pregnant from conception date is it possible for the ultrasound to be off by 4 weeks and be 11 weeks pregnant?

No it is not possible to be 11 weeks instead of 7 weeks pregnant. Ultrasound is reliable for dating within a 2 week error. So it is possible for you to be 4 weeks or 9 weeks but not 11 weeks. However dating is usually based on the last menstrual period unless there hasn't been one.


Is diarrhea a sign of pregnancy or miscarriage?

Answerno---I think it possibly could be a sign. My baby stopped growing 6w2d and my diarrhea started that day, but I did not miscarry for 3 weeks. Once the baby stopped growing, I had diarrhea for 7 days straight - and that never happens to me.Now I am pregnant again & I hit 6w2d yesterday and my diarrhea started again. The doctors feel my baby will not make it based on my 6w1d ultrasound, so this diarrhea could be a sign in my 2nd miscarriage.

Is your pregnancy normal if the ultrasound scan reveals you are 5 weeks pregnant with the gestational sac and yolk sac minus fetal pole but based on your last menstrual period you ought to be 9 weeks?

There are two answers to this - one good and one bad. The most probable answer is that you miscalculated and you are actually 5 weeks pregnant. Unfortunately there is a possibility that you did fall pregnant 9 weeks ago and that the pregnancy will not progress. It is possible that either the fetus is not developing, or that the fetus has died which usually means the gestational sac will shrink and appear to be not as advanced as you are.


Should a pregnancy test be positive 4 weeks after miscarriage having started a period?

You can still be tested positive after a miscarriage and a period. A pregnancy test is based on the levels of hormone you have in your body. It might not have gone back to normal. And your bleeding can be caused from the miscarriage itself and doesn't necessarily mean that is a period. Check again in a week or two and then ask your doctor if it still shows up positive just to make sure that you really aren't pregnant.

Certainly, contrary to old beliefs and myths. Becoming pregnant is based upon your period as much as it based upon your ovulation which is about 14 days before your period.

If an ultrasound gives you a date of how far along you are is it possible you could have been pregnant 5 weeks ago and still had your period and the ultrasound be off?

The ultrasound doesnt give you the date. It is estimated by the days you give to the doctors to help, narrow down the date. The first day of your last period and how long you've missed help them in determining your conception date. The picture shows them an image of a fetus and they use that picture to say at what developmental stage the baby is in. Anything is possible.AnswerContrary to the opinion above, the ultaasound does give you an approximate date of conception. By comparing the results of millions of ultrasounds physicians can calculate the age of the fetus based on head diameter, bone length, and other measurements on the fetus. They are usually accurate to within two weeks of when you are due to deliver. Since some women have irregular periods, it is not always possible to calculate the date based on the first day of the last period. Trust the ultrasound! ANSWERI just wanted to add to the above answer. A patient's Last mentrual period is accurate if the patient has a regular mestrual cycle, but this is not the case for many women. Therefore, it is not the most accurate source for fetal age. Ultrasound is the most accurate dating tool for fetal age. The measurement of the embryo (crown rump length) up to 12 weeks gestation is the most accurate. The rate of growth of a fetus will be based on that early measurement for the remainder of the pregnancy. It allows physicians to monitor the growth of the fetus which in turn gives them an estimated due date as well as help them diagnose growth abnormalities such as IUGR (Intrauteriune growth restriction).
