Early Scan and Symptoms

Arianna
Hi Ladies I am 5 wks and 3 days pregnant today. Due to have some pain in my lower abdomen the hospital did an early scan yesterday. The pregnancy location was unknown. So i had a blood test to check my Hcg levels and will follow up in 2 days with another test. Has anyone had this happen to them and then had a miscarriage or ectopic pregnancy? Also I've not had anymore cramping, nausea etc. Is that a bad sign? I'm really worried somethings going to go wrong. It's also my first pregnancy after years of trying.
