Girls, hi ? Has anyone tried oxygen cocktails? I don't have any indications, my tests, ultrasounds and so on are good. The gynecologist just advised me to drink them for prevention. The only thing is that there's a lot of bleeding with these cocktails, you need to buy special equipment to make them at home, and it's not cheap either. Of course, I'm not worried about the child, but will this be beneficial?
