Don't panic, we are talking about the pregnancy test stick, not antigen Ha!
Staying at home for such a long time, and being with his teammates every day, Xiaobian understands ~ looking at the two red bars on the pregnancy test stick, I can't believe my eyes! Surprise? Scare?
Even during the epidemic, when pregnant at 6 to 8 weeks, it is best to go to the hospital for an early pregnancy ultrasound. After all, it is related to whether the pregnancy is successful? Is there a fetal heartbeat?
Li Li, who has been actively preparing for pregnancy, has been happy since the "two bars" were detected. But when she went to go to the early pregnancy ultrasound, the doctor told her that "there was insufficient evidence of intrauterine pregnancy", and then several times the HCG was tested, one time lower than the other, and the doctor told her that it may be biochemical.
Similar to the encounter is also Xiao Jiao, obviously the first ultrasound also saw the fetal heart, but when the second B timeout, the doctor said that the fetal heart could not be found, the embryo has died.
For whether you are pregnant normally, compared to the HCG test, B ultrasound is more accurate! The two bars may be happy to run, but there are also regrets that come from sorrow.
However, after the examination and the report, did I not understand it: "Doctor, am I pregnant?" Why can't I see my baby? "Today I will take you to learn to read the ultrasound report of early pregnancy."
The old rule is to look at the ultrasound prompt first, and then look at the ultrasound description.

Ultrasound suggests: there is currently insufficient evidence of intrauterine pregnancy
Obviously two bars, why do you say that you are not pregnant?
There is a window period from positive blood or urine hCG to ultrasound finding of the blastocyst, when hCG produced by trophoblasts can be detected in the urine or blood, but the volume of all cells can not be recognized by ultrasound, and the ultrasound concluded during this time that "there is currently insufficient evidence of intrauterine pregnancy".
If there are no abnormal symptoms such as redness and abdominal pain, you can wait about 5-10 days before repeating the ultrasound. But if the abortion occurs during this time, the HCG gradually drops to normal, like menstruation, it is "biochemical pregnancy", that is, pregnant with loneliness.

Ultrasound prompt: small cystic structures in the uterine cavity
Cystic structure? So is it pregnant?
Well, it's still a matter of time. The earliest form of the gestational blastocyst is an echoless, although ultrasound has a "bicyclic sign", but it can not be concluded that "pregnancy" cannot be concluded until the yolk sac is present.
We usually very conservatively suggest "small cystic structures in the uterine cavity", which is a sign of rigor.

Ultrasound prompt: intrauterine pregnancy
This means normal pregnancy, right?
Yes, the yolk sac usually appears after 5.5 weeks of pregnancy, at which point it is clear that the embryo is implanted normally in the uterus.

Ultrasound tips: early pregnancy in the womb
Can that be seen as a few weeks pregnant?
Generally, the germ will begin to appear at about 6.5 weeks, and the original cardiovascular beat will appear around 7 weeks, that is, the "fetal heart". There is a calculation method for gestational age: gestational ≈ 6.5 + germ length (cm).
For example, in this figure, the germ length is 1.5cm, so the gestational age is about 6.5 + 1.5 = 8 (weeks), this formula only applies to the first trimester, which is a more accurate way to infer gestational age. If the menstrual cycle is irregular, the estimated gestational week is generally based on the inference of the first trimester!

Ultrasound prompt: intrauterine pregnancy, fetal heartbeat is not seen
Maybe the last time I saw the original cardiovascular beat (+), how did there be a little blood or no heartbeat when I came to the obstetric card?
Due to a variety of factors, some of the less "excellent" embryos die of natural selection, and in most cases it is a matter of embryo quality, which is a process of natural selection.
If the fetal heart rate appears first and then disappears, it is impossible to grow again; or the embryo grows to 7 mm without a "fetal heart", it belongs to the blastocyst withering. In addition, there is no yolk sac when the average inner diameter of the blastocyst exceeds 20 mm; or the average inner diameter of the blastocyst exceeds 25 mm and there is no germ; or the blastocyst does not grow for several days or even a week, which are all manifestations of "inevitable miscarriage" (inevitable miscarriage).
If abortion is unavoidable, there is no need to wait, and an appropriate method should be chosen to terminate the pregnancy.
In addition to normal pregnancies, there will also be ectopic pregnancies (commonly known as ectopic pregnancies). Most of the sites of ectopic pregnancy blastocyst implantation are in the fallopian tubes, and others include cervical pregnancy, caesarean section scar pregnancy, ovarian pregnancy, abdominal pregnancy and so on. There are also trophoblastic-related diseases such as mole, erosive mole, and trophoblastic tumors such as chorionic carcinoma. The above abnormalities require professional diagnosis and treatment, at this time to listen to the professional opinions of the attending doctor.
So with the "two bars", in addition to normal intrauterine pregnancy, there are many other abnormal possibilities, remember to do ultrasound in time.
