Hello, and I hope I can help you today.
There are two possibilities of what could be going on with your
pregnancy. If you really did conceive back in October, your pregnancy should be about 12 weeks. This would have been found on the
ultrasound examination that you had but instead the fetus measured only five weeks three days. At five weeks it is not normal to see fetal heartbeat so that is not used in the consideration to make a diagnosis.
However, it is possible that you conceived later in the cycle after your. In October. If you actually conceived in late November early December it is still possible that the fetus could be viable and that is just younger than it should be by your dates.
So the way to tell the difference would be to get another ultrasound examination and approximately two weeks; by then you should see some evidence of the fetal heartbeat if the pregnancy is normal.
Contrary to popular belief, the majority of women do not have pregnancy symptoms. The most reliable sign of pregnancy is a missed menstrual cycle. Furthermore, judging the number of weeks of pregnancy on a urine tests is extremely inaccurate.
Pregnancy tests are designed to pick up the hormone
hCG from that which comes out in your urine. However, your urine can be diluted by different amounts of water depending upon what time in the day you tested and how much water you drank beforehand. Most urine pregnancy tests ask that you use your first morning urine, which has the most concentrated sample, however, even within those restrictions there is a large margin of error.
So I would advise, in your situation, that you repeat the ultrasound examination in another 2 to 3 weeks. In the meantime take good care of yourself for the pregnancy by: eating a well-balanced diet, drinking lots of water, and taking
prenatal vitamins.
Best wishes, and good luck with the rest of the pregnancy,
Dr. Brown
