The way I understood it these blood clots are a different kind of blood clot, and almost always deadly. But the amounts of "accepted" blood clots with the contraceptive pill are quite horrific.
I believe a lot of people are missing the point here that you can choose whether or not to the take the pill. Many women I know choose not to take it because of health side effects. The issue of side effects with vaccines is a lot of people feel like they are being coerced through talk of vaccine passports and other measures.
