A Lil confused?? Could you potentially have a mestrual cycle or spot bleeding for a couple of days while potentially been pregnant.

I been having super light period no cramps no backache not even clogs. At fist it was a black brown color then it got a Lil lighter but not a true red. My husband has check my cervix position and its high soft closed. So I'm confused ....could I be pregnant? I thought it had to be low open and soft for mestrual cycle? Has this ever happen to anyone else?
