Mixed bleeding..sometimes brownish sometimes red and sometimes mixed 26 days post m/c(blighted ovum)can i get pregnant while bleeding..sex safe!

Yes: There is a possibility that you can get pregnant while you are bleeding. Use contraception at least for 1-2 cycles.

Miscarriage bleeding: How far along were you when you miscarried? Usually by 3 weeks after a miscarriage/ birth bleeding has stopped, so I would be evaluated by an Ob-gyn and assure there are no additional issues before resuming intercourse, as this may not be bleeding from a period.
