Excuse me, how long can pregnant go to check ectopic pregnancy

Ectopic pregnancy, also known as ectopic pregnancy, refers to the implantation of fertilized eggs outside the endometrium. After 6~8 weeks of menopause, abdominal B-ultrasound can be used to check whether there is a gestational sac in the uterus. If the patient has obvious abdominal pain or vaginal bleeding, it may be caused by ectopic pregnancy. HCG determination and laparoscopic diagnosis should be done in time.
