Ok so my period was supposed to show yesterday but I've been very lightly spotting mostly brown but some pink blood lately. My cervix is low kind of hard but also soft and I can only feel it when I'm sitting down if I try to prop a leg I can't touch it at all. I can't tell if it's closed or not...I'm so confused on what's happening this has never happened normally my period shows up and is strong for 4 days and then done til next month..but every test I've take. Is negative? Any thoughts what could be going on?
