Dear girls, it's become a bit scary, there was an IUD in August, and in September the first period came, they were normal, now the second period has come but it's flowing like from a bucket for a day (sorry for the details) I can't get up, I can't even cough because it starts bleeding immediately, is this normal? Friends who had an IUD say that it's normal, they also had it like that, but I'm scared because the IUD was heavy, there was also blood transfusion, by the way, my blood pressure is 106/68, I'm afraid that it's a hemorrhage, and maybe these periods are like that
