No gestational sac found, only dark areas

Early pregnancy is usually tested with test strips, but this method varies. In the later stages, you will need to go to the hospital for B-ultrasound examination to rule out ectopic pregnancy. Some women go to the hospital for a check-up and find that they cannot find the gestational sac, only a dark area. They are definitely very worried about this situation, fearing that there is a problem with their pregnancy. So, why can’t we find the gestational sac and only the dark area? Let’s take a look below.

Generally, the gestational sac is seen around 40 days of pregnancy. If you still haven't seen the gestational sac on 38 days of pregnancy, it may be caused by your long menstrual cycle and late implantation of the fertilized egg. It is recommended that you have another ultrasound check one week later to confirm intrauterine pregnancy and exclude the possibility of ectopic pregnancy.

Clinical manifestations of ectopic pregnancy

1. Menopause

Except for pregnancy in the fallopian tube interstitial region, which lasts for a longer period of time, most cases last for 6 to 8 weeks. 20% to 30% of patients have no obvious history of amenorrhea, or their menstruation is only delayed by two or three days.

2. Vaginal bleeding

After the death of the embryo, there is often irregular vaginal bleeding, which is dark red in color and small in amount, generally not exceeding the amount of menstruation. A small number of patients have heavy vaginal bleeding, similar to menstruation, and may be accompanied by the discharge of decidual fragments.

3. Syncope and shock

Due to acute intra-abdominal bleeding and severe abdominal pain, mild cases may experience fainting, while severe cases may suffer from hemorrhagic shock. The more and faster the bleeding, the quicker and more severe the symptoms appear, but they are not proportional to the amount of vaginal bleeding.

Ectopic pregnancy prevention

1. Pregnancy and proper contraception

Choose a time when both parties are in a good mood and physical condition to get pregnant. If you are not considering becoming a mother for the time being, you must take good contraceptive measures. Good contraception fundamentally prevents the occurrence of ectopic pregnancy.

2. Timely treatment of reproductive system diseases

Inflammation is the main culprit for fallopian tube stenosis. Intrauterine operations such as artificial abortion increase the chance of inflammation and endometrium entering the fallopian tube, which in turn leads to adhesion and stenosis of the fallopian tube, increasing the possibility of ectopic pregnancy. Reproductive system diseases such as uterine fibroids and endometriosis may also change the morphology and function of the fallopian tubes. Timely treatment of these diseases can reduce the occurrence of ectopic pregnancy.

3. Try IVF

If you have had an ectopic pregnancy before, you can choose in vitro fertilization. After the sperm and egg successfully "get married" in vitro, the fertilized egg can be sent back to the mother's uterus for safe gestation.

4. Pay attention to hygiene during menstruation, delivery and postpartum period to prevent infection of the reproductive system. Determine the location of pregnancy as soon as possible after menopause to detect ectopic pregnancy in time.
