Possible Pregnancy?

Danielle
I can't find any accurate information of this on the internet. Maybe someone can help me. My husband and I had sex in my fertile window now I'm over a week late on my period. My periods are normally very regular. So being late is very unusual for me. I took a pregnancy test but it came back negative so I decided to check my cervical position and fluid. This is what I can't find any information about. My cervix is low, soft, and definitely closed. My cervical fluid is creamy and white. (tmi) I have absolutely no symptoms of any kind. No period symptoms or pregnancy symptoms. I'm very tired and thirsty but that's it. What could this mean? Is this a sign that I may be pregnant?
