Question: can an ectopic pregnancy be detected at 6 weeks?
Answer: An intra-uterine pregnancy can usually be seen by 5-6 weeks gestation or when the HCG level is >1500 IU/l. If it is not in the uterus, it may be ectopic. In 95% of ectopic pregnancy cases, a good transvaginal ultrasound examination can actually see the ectopic pregnancy in the Fallopian tube.
