Hello doctor. This is my first pregnancy, my period was due on February 5th, on February 3rd I had a slight pain in my lower right abdomen (I went for an ultrasound at a clinic near my house using the paracentesis method) but the gestational sac was not seen. Today, February 6th, my period is 1 day late, the pregnancy test showed two lines (the remaining line is very dark like the previous line).

Ultrasound is very beneficial in diagnosing ovarian tumors, this is a non-invasive imaging diagnostic tool and provides high accuracy. In particular, ultrasound classification of ovarian tumors will help doctors make decisions on surgery, treatment or monitoring to ensure the best health for patients.

Cesarean scar defect - uterine cavity fluid is a major concern recently. In recent years, the rate of cesarean section has increased due to professional factors and additional social factors. Cesarean scar defect is a phenomenon recorded 1-2 years late and can be 10 years after cesarean section, due to poor scar recovery in the uterine isthmus. This can be considered one of the causes of secondary infertility.
