Need help.

Okay I can't tell if my cervix is open or closed! I have given birth to four beautiful children. I know that is you gave birth before your cervix will feel like a slit instead or a hole. But I can't tell if it is closed or not.... my cp is everywhere and it's going soft and firm all day long it also going from creamy wet and dry also. . I have four days before af and on CD 22.
