series of tests on me saying I am pregnant but the sac is not in sight.
have abdominal pains or anything of the sort.
are tender, my stomach looks slightly bloated and I am having all
the signs of a normal pregnancy.
really confused, help me.
gestational sac can be due to
ovum : also known as anembryonic pregnancy.
pregnancy (sometimes termed a blighted ovum) is a gestational sac
which develops without a fetal pole.
pregnancy (intrauterine) : by 5 weeks gestational age, a yolk sac
should be identifiable by transvaginal ultrasound.
intrauterine pregnancy is a pregnancy that happens inside of the womb.
sac with an ectopic pregnancy.
sac is an intrauterine anechoic sac-like structure that may be mistaken
for an early viable pregnancy.
pregnancy is a complication of pregnancy in which the embryo implants
outside the uterine cavity.
trophoblastic disease : some first trimester moles may mimic a blighted
ovum; correlation with beta hCG is helpful.
trophoblastic disease is a pregnancy-related condition that can occur
in the uterus after conception. The term gestational trophoblastic
disease (GTD) actually describes a group of rare diseases that begin
in the tissues that are created after conception, i.e., the joining
of egg and sperm in the uterus. GTD is so named because the disease
begins in the trophoblast, the layer of cells that surrounds the newly
types of gestational trophoblastic disease can develop into cancer,
which is why its important that they be diagnosed as early as
or Human chorionic gonadotropin is a hormone produced during pregnancy.
beta subunit of hCG, Beta HCG "the pregnancy hormone", is
produced by the cells of the implanting egg and can be produced in
the absence of an embryo.
