Cervix and pregnancy

Sarah
So for the first days (probably about 2 weeks actually) after ovulation my cp was high open and soft... Now it's kinda mid and soft slightly closed, I'm 4 days late, been sick, wanting to eat everything but nothing sounds appatizing:/ moody as hell and just wanna sleep:/ took a pregnancy test a day before AF was due and it was negative... Any ideas? Should I retest? I ovulated 2x once on CD4 and once on like CD12/14 proven by positive OPK's today is now CD 25
