I asked google for Yank miscarriage stats. This was the first answer:

For women who know they're pregnant, about 10 to 15 in 100 pregnancies (10 to 15 percent) end in miscarriage. Most miscarriages happen in the first trimester before the 12th week of pregnancy. Miscarriage in the second trimester (between 13 and 19 weeks) happens in 1 to 5 in 100 (1 to 5 percent) pregnancies.

The second link (here: https://www.mayoclinic.org/diseases-...s/syc-20354298) reports:

About 10 to 20 percent of known pregnancies end in miscarriage.

Meanwhile, this US billionaire said on Fox News he believes "hundreds of thousands" of Americans have been killed by Covid vaccines. Their excess mortalities (excluding Covid deaths) is currently running at 19,600 per week.
