5 weeks no yolk sac or fetal pole

Andria
Hello everyone. I'm so new to this and have no idea what to expect. I went to the ER because I was having cramps really bad. They did an ultra sound and said they didn't see a yolk sac of fetal like. They did see a Ges sac. They worried me sick with the negative comments. My hgc levels have been raising like they should. Is this normal? Is it to early to see anything yet?
