Patient's question:
I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried it might affect fertility, and I'm also extremely sensitive to cold and coldness. Is it possible for a gestational sac to be in the fallopian tube?Doctor's answer:
Generally, once it enters the uterus, it will not return to the fallopian tube unless there is a blockage or a condition where it is not fully open. Previously, it had implanted in the fallopian tube. Down syndrome, also known as trisomy 21, refers to a condition where the patient has an extra chromosome 21 (while the normal number is one pair). The Down syndrome screening is calculated by measuring the levels of AFP and HCG in the pregnant woman's serum, combined with the mother's age, weight, and gestational week to determine the risk value. The critical value is 1/275. A value greater than this indicates high risk, while a value lower than this indicates low risk. The probability of having Down syndrome (DS) in the general population (under 37 years old) is 1/750.
