I'm 8 weeks, 1 day today base on my last menstrual period. I did my first ultrasound yesterday but only gestational sac was seen. No fetal pole or yolk sac detected yet. The sonographer suggested late conception and advised to come back in 2 weeks time. But it's already 6 weeks since I tested positive. So even if there was late conception, I am definitely not less than 6 weeks pregnant. Has anyone else experienced this and later saw a baby with heartbeat? I'm worried please. What should I do? So far, I'm still having symptoms and I haven't experienced any form of spotting or bleeding since I conceived.
