I think my estrogen is a little highish and my progesterone a little lowish but I guess within normal range since I wasn't informed of any abnormalties.

I believe it's because of low progesterone or prolactin. http://www.breastnexus.com/showthread.php?tid=21572

During luteal phase, raise progesterone and prolactin. Prolactin can be raised by mood and certain foods, and prolactin raises progestogens. Having uncomfortable or long periods is a sign of too low progestogens and high estrogen. Your estrogen and testosterone levels may be fine, it just needs more progestogen or prolactin balance.
