early pregnancy

Christie🌈👶🏼💙💙
I need some answers girls...I had a scan today but they couldn't see anything but I only have 2-3 weeks pregnancy,I had an ectopic in April and I'm a bit scared,they said maybe it's too small to be seen at scan did you had something similar?really will help me keep my hopes on until I have another blood test to see the level of the hormones thanks
