No Period Not Pregnant?

Al

Hi! I’m in a bit of an anxious rut right now. My period is now 13 days late, but I have occasional “pre-period” cramps every now and then. My boobs have been sore for the past two days, but absolutely no sign of a period. My husband is convinced we did not have sex this past month, but I for the life of me cannot remember.

I do have PCOS and went through a schedule change that I thought was maybe what was making it late. I was getting no sleep and my nutrition was lacking. My period is super regular otherwise.

I will be taking a pregnancy test Saturday. Does anyone have any thoughts on what is going on?
