I am exactly 5 weeks from my lat LMP with positive pregnancy test. There was no sac seen in the uterus and the doctors suspect it could be ectopic pregnancy. My blood Hcg yesterday was 877. Whoever is pregnant or was pregnant can please let me know if a sac was seen for you by 5weeks of pregnancy also what was your hcg around that time. Guys Please please reply. I am really worried. If it is ectopic what signs should I be looking for to go into emergency.
