My period us usually 7 days and super heavy for 3/4 days the medium for the following 3/4 days. This month it was only 4 days the first 2 were super light brown followed by 2 super heavy days. And it was over. I've had headaches for the last week along with light headed dizziness. Dry bloody nose backaches and today a stiff neck. What is up? Is this pregnancy or a goofy period ttc for a year now.
