Preseed baby or miscarriage?

If you’ve used Preseed or anything like that, did it lead to a healthy baby or a miscarriage?

We used Preseed back in May for the first time and got pregnant, however MC at 7 weeks.

We are trying again but now I’m nervous to try Preseed again if it’s possible that it lets the “bad” sperm get to the egg first. I’ve ready things like that before but also have read many success stories 🤷🏽‍♀️
