Bear with me on my post as it may be long...
1st pregnancy was a twin pregnancy but I didn't know at the time (not IVF) had lots of bleeding but no epau at that time so was dismissed as mc. At 11weeks I had a scan and one baby, two sacs, gave birth at 40wks to one healthy baby and one mummified baby in the other sac.
5 th pregnancy was IVF, two babies at scan at 7wks, scan at 9wks there was one baby. Had no bleeding at all. Sac kept growing until 23 weeks, I had a big bump.
It doesn't mean mc. Hope this gives you hope xxx
