Early Pregnancy @ 5weeks

Hi,

I tested positive on 3 PT last april 23.

I had a transvaginal ultrasound yesterday and the sonologist haven’t seen a gestational sac, but there is a part in the ultrasound report that says

“Within the endometrium is a cystic structure measuring 0.42cm x 0.21cm probably representing the gestational sac”

I am very anxious but before i took the ultrasound i was advise to go back next friday when i am on my 7 weeks.

I just wondered if anyone has experience this? I am 36yo and i am worried sick and getting paranoid of ectopic pregnancy or something else.
