Need help first time this happened!!!!! Less then 5 weeks

Aleacia

So I had horrible cramps I found out I was pregnant it was a complete surprise I went to the er and my HCG level was 3,015.. however they seen the gestational sac and a normal Yok sac but they did not see a fetal pole or detect a fetal heartbeat... in hopeing I’m just to early but I need some reassurance because of course the er doesn’t tell you anything....
