most likely you are simply too early for the ultrasound to see the pregnancy. another possibility is that you are having a very early miscarriage, often called a "chemical pregnancy" which means that you for pregnant but it didn't take. the only way to know for sure is to wait and see how things develop over the next two weeks or so. if the pregnancy is ok, it will grow and be visible on ultrasound. if it is not ok, you will have some bleeding and cramping and pass it and the blood tests will show the hormone levels dropping. te endogest is a hormone that is meant to support the pregnancy, just in case the problem is related to a deficiency in progesterone. there are minimal side effects when you only take it for a few weeks, and it is safe for your baby. I hope this helps, please let me know if you have any more questions.

Hi, Thanks for the query.

Sometimes the pregnancy occurs later than what is predicted by the date of the last menstrual period. This may happen due to delayed ovulation. If the pregnancy is very early, sonography will not detect it. Sonography will not pickup anything less than 5-6 weeks.
Another possibility is a missed abortion when the fetus is not alive. Urine test is still positive and it may rarely fail to show any sac on sonography. Ectopic pregnancy can also produce a similar picture when the uterus is empty and the pregnancy test is positive. This can rupture. It will give rise to symptoms like pain in abdomen, palpitations and fainting if it ruptures. A serum beta HCG done twice at an interval of 48 hours also helps to detect ectopic. Transvaginal sonography [TVS] also picks it up early. Check to see if you had a vaginal scan or sonography was done from the abdomen. If it was an abdominal scan, get a TVS done.

Now about endogest: This is a hormone similar to progesterone, a natural hormone that helps to maintain the pregnant state. If levels of progesterone fall then abortion may occur. Since you are having a positive urine test, this has been given as a safeguard to maintain pregnancy.

This can be taken orally or if it is a soft gelatin capsule may be taken vaginally. Also I suggest that you get a follow up scan done after 2 weeks, preferably by TVS, to confirm pregnancy.

Hope this satisfies your query.

Feel free to ask any more questions that you may have.
