hi derekaustin2011 ,
I Have read your Question,
Without physical examination , I cannot conclude anything , but mostly it looks like you are anemic or you may be suffering with hormonal
irregularity.These issues generally cause ,nausea
, and light periods due to lack of blood.
I suggest you to take Iron -rich food like green leafy veggies, dates , pomegranate juice , jaggery , haemotonic for relief .
But if the problem still persists , I recommend you to consult a nearby gynecologist for further advice.
Wishing you a good health,
