Thanks for posting your query. According to your LMP (last menstrual period) you are at 6 weeks gestation.
The normal values of HCG
for 6 weeks are usually 1080 to 56,500 MIU/ML.
Your value of 894 is a little low. But these values can vary a lot and are only guidelines, and many women with low HCG values can have a normal pregnancy
A low HCG value may be recorded due to many reasons. The most common would be a miscalculation of the dates.
Other serious causes would be ectopic pregnancy or miscarriage
No decision can be made on a single HCG value. It is important to take another test about three days later to check if the values are rising.
Also an ultrasound
examination to confirm uterine pregnancy and rule out ectopic is essential.
If your HCG values are rising in subsequent tests and ultrasound shows uterine pregnancy, then there is no cause for worry.
In case of low values your gynecologist will guide you about HCG support during pregnancy.
Hope I have answered your query.
