I'm just sorry you're going through this, Bumble.
I was in your shoes early last month.
For me, however, at the third scan - the second transvaginal one - there was no growth at all over the course of a week, and no heartbeat, of course.
I went for the D&C because for me, it was really the best course of action.
My body was NOT expelling hte pregnancy.
I also live in a rural area and if something goes wrong out here, the consequences could be severe.
BUT, that being said, I'm glad there was that wait between teh two transvaginal scans, because at the second one, I saw the screen and I knew my baby hadn't made it.
The GYN who did my D&C wanted to be sure, maybe for his sake, it didn't matter. So I said, 'Sure, do another scan. But I don't want to see it.'
And yes, the baby hadn't made it.
I just hope things work out differently for you and if not, then I hope you make a decision that's best for you and know that you can come here for support.
