I should have had my period this week, but instead on Sunday night into Monday morning, I cramped all night and woke up to a pinkish tint when i went to the restroom. The remainder of the day was very light brown discharge. It is now Thursday, and I cramped this morning, but it continues to be very light brown discharge, and only when I go to the restroom. I have been off birth control for 5 years no with no pregnancies. My vision has been somewhat blurry when looking at the computer at work. I have a headache just as when I have my period, but still nothing. I have had instances in the past where my period was slow to start, but never 4 days. I ve also noticed that smells are stronger and my appetite isn t really that big. I am 36 with two boys ages 12 & 15. I took two pregnancy tests on Tuesday (First response), and one yesterday (Wednesday). All 3 are negative. Can this really be pregnancy symptoms?
