When is it safe?

When is it safe to masturbate after a d and c??? Or should I say when did you guys masturbate after? I've been horny but I'm scared to because I've read online that some people said that it has hurt really bad when they orgasmed and started bleeding again but also some had said it was refreshing and also did it to clean themselves out... I dont know what I should do...part of me wants to but part of me is so scared.
