Need some help please any opinions please

For those of you who had there period while pregnant whether it was the whole time or part of the time. Do you know what your cervix felt like while you had your period? I know when your pregnant it is supposed to be high soft and closed. But if your not pregnant and you get your period, before you get it your cervix is low hard and closed. On your period it is low hard and open. So I guess my question is, if your pregnant and you have your period or break thru bleeding is your cervix then low hard and open or is it still high soft and closed???
