Went for an early scan today as I've been having severe cramping (no bleeding though). I'm 6+3 by date of LMP, or possible 5+3 by ovulation date, but certainly no further behind than that. Saw a sac with nothing in it; Dr said that he would expect a healthy pregnancy to be further along at this stage, even accounting for my longer-than-usual cycle length. I have to go back in two weeks for another scan to confirm.
I had a full-term neonatal loss last year, and a mmc earlier this year. Can't believe this is possibly happing again.
