just got another text from her.
it looks like a sac, a small one but one none the less. they'll monitor her levels for a week then if they go up they'll do another u/s fingers crossed they rise like crazy for her and she has a bubba in her arms in 7 months time...
I had an internal just before 6 weeks. They saw sac but nothing else, was told that's very normal and not to fret or get attached. Heartbeat seen at 7w5d. Now 16w

It's too early either way to give her a definitive answer.
