Patient's question:
My girlfriend went for an ultrasound five weeks after her last menstrual period on October 24th, but the ultrasound did not show a gestational sac in the uterus. The size of the uterus was 4.6×6.8. However, the blood test confirmed pregnancy with HCG levels of 485. Additionally, my girlfriend has been experiencing occasional lower abdominal pain recently. I’m not sure if it could be an ectopic pregnancy. But the doctor advised us to wait a few more days for a follow-up check-up. Three days later, a vaginal ultrasound was performed, which showed no fluid in the pelvis and a cystic lesion on the uterine wall, measuring 4.5mm×5.Doctor's answer:
Hello, the occurrence of ectopic pregnancy is not very common. This is when the fertilized egg implants outside the uterus. Implantation of the fertilized egg inside the uterus is a normal pregnancy. If it implants outside the uterus, it is considered ectopic pregnancy. There are many factors that can lead to ectopic pregnancy. Insufficient movement of small villi in the fallopian tubes is a major factor, which prevents the fertilized egg from reaching the uterus normally for implantation.
