BK,
Spotting or a brownish discharge a few days before the period is usually a sign that the level of progesterone in the blood is decreasing earlier than normal.
In a normal menstrual cycle, the level of progesterone falls a day or two before the period occurs. Since progesterone helps support the endometrium (inner uterine lining) in the later part of the menstrual cycle, this fall causes the endometrium to shed. Shedding of the endometrium and the subsequent bleeding causes the menstrual period. You can read about the menstrual cycle here:
Normal Menstruation Cycle
Spotting before the actual menstrual period means that the level of progesterone is not adequate in the body at this time. This can be due to either failure of ovulation or a condition known as Luteal Phase Defect (LPD).
LPD is a condition in which the corpus luteum which forms after ovulation is not producing enough progesterone to mantain the endometrium. A luteal phase defect can also prevent or hamper implantation of the embryo.
A short menstrual cycle is also an indication of a LPD.
You can read about the causes of Female Infertility here:
Causes of Female Infertility
The standard treatment in LPD is to prescribe progesterone tablets (either medroxyprogesterone or micronised progesterone) from the 16th to the 26th day of the menstrual cycle (the first day of active bleeding is the first day of the menstrual cycle).
Please consult an Obgyn for an examination and a confirmation by ultrasound that you are indeed ovulating.
I hope this helps.
