However, our analysis proved that these numbers were extremely misleading due to the fact that of the 827 completed pregnancies, 700 / 86% of the women had received a dose of either the Pfizer or Moderna Covid-19 vaccine during the third trimester of pregnancy, meaning it was impossible for them to suffer a miscarriage due to the fact they can only occur prior to week 20 of a pregnancy.
This meant that just 127 women received either the Pfizer or Moderna Covid-19 vaccine during the first / second trimester, with 104 of the woman sadly losing their baby.
Therefore the rate of incidence of miscarriage was 82%
You have to read the actual study to realize that 127 isn’t the denominator. Many more were still pregnant. The table they are getting those numbers from doesn’t make this clear.
“Among 3958 participants enrolled in the v-safe pregnancy registry, 827 had a completed pregnancy, of which 115 (13.9%) were pregnancy losses and 712 (86.1%) were live births (mostly among participants vaccinated in the third trimester).”

How many vaccinated in the first trimester were still pregnant?
