Just that really. Period is 6 days late. I am not pregnant. I have done two pregnancy tests and both were definitely negative, not even a hint of a line.
I know that periods fluctuate but I have literally never had a late period in my life except for when I was pregnant. They are every 28 days like clockwork. I have never used hormonal contraception - I have the copper coil. I am 31.
It's freaking me out. Any ideas?
