Is transvaginal ultrasound accurate in detecting early pregnancy?
3 doctors weighed in across 2 answers
After 5 weeks: A vaginal ultrasound is not as sensitive as the urine or blood pregnancy test. After about 5 weeks the ultrasound will show a very early sac in the uterus. After 6-7 weeks fetal heart activity is frequently seen. The pregnancy test can be positive before the first missed period.

Yes: At 5-6 weeks a gestational sac and pregnancy reaction can be seen. At about 7 weeks a tiny fetal pole and heartbeat can be seen. At less than 5 weeks, nothing may be seen so would need to check blood and urine results before planning for sono.
