Days late and still negative

Laura

Ok. I writing this in hopes that I can get some answers or some advice from some of you ladies. As of today I am 10 days late for my period. When I was about 3-4 days late I went and had blood work done to see if I was pregnant and it came back negative as well as the test strips at home. I have not had any symptoms or signs of my period coming like inormally do so I'm really confused. Anyone ever experienced this before? Any idea what it might be? Anything would help. Thank you.
