Is it possible at six and a half weeks pregnant to have an…

It is difficult to determine the viability of a pregnancy based solely on the level of progesterone in the blood. Progesterone levels can vary greatly during early pregnancy and are influenced by many factors.

However, a progesterone level of 8.1 ng/mL at six and a half weeks of pregnancy is considered low and may indicate a higher risk of miscarriage. Normal progesterone levels in early pregnancy can range from 10 to 29 ng/mL.

In general, there is some evidence to suggest that progesterone supplementation may be helpful in reducing the risk of miscarriage in certain populations, such as women with a history of recurrent miscarriage or those with progesterone deficiency. However, there is not yet a consensus on the optimal dosing, timing, or duration of progesterone supplementation.

It is understandable to feel nervous and anxious about your pregnancy, especially if there are uncertainties or potential concerns. It is good that you have another ultrasound scheduled, as this will provide more information about the development of the pregnancy and hopefully give you some reassurance.

It is possible that the lack of a visible yolk sac at the first ultrasound was due to incorrect dating, as the gestational age may have been too early to see the yolk sac. However, it is also possible that there may be other issues affecting the pregnancy, such as a blighted ovum or delayed development.

Best wishes to you
