Hi, Progesterone usually increases prior to a womans period and cause the period to arrive in some cases. Low progesterone may cause spotting but so does pregnancy.
Blood levels of estrogen and progesterone decrease.
Estrogen and progesterone levels begin to increase prior to mensuration.

"The corpus luteum synthesizes progesterone, estradiol, and 17-hydroxyprogesterone. The increased progesterone levels affect the thermoregulatory site in the hypothalamus and increase the core body temperature. Negative feedback from the increased release of estradiol and progesterone from the corpus luteum results in decreased serum LH and FSH levels in the luteal phase. If conception has not occurred, FSH levels increase again at the end of the luteal phase as the progesterone and estradiol levels decrease. The decrease in progesterone and estradiol levels results in shedding of the endometrium-i.e., menstruation. LH pulse frequency is high (90 minutes) and of low amplitude in the follicular phase. The pulse frequency and amplitude increase immediately before ovulation".
decreased levels of luteinizing hormone (LH)
yes it could if you've had a positive pregnancy test, could be low progesterone levels needing supplement or threatened miscarriage I'd ask my doctor to draw a progesterone level, I did the same and had to miscarry my first before the doctor checked. they usually want "history" which i think is crazy.
estrogen and progesterone
Yes
It depends on your levels. Typically, progesterone is taken from the very beginning of pregnancy (sometimes before) until about 12 weeks, when the placenta takes over the functions of the ovaries. Frequent blood draws will indicate when you can begin weaning off the progesterone.
Progesterone levels rise after ovulation to protect the fertilized egg and to prevent the uterine lining from shedding.
Well, its pretty simple. If you are spotting, you are spotting. If its your period you will be bleeding constantly. When womnen spot it is usually just spots of blood, not even enough that you have to where a pad or tampon. When on your period, you would not dare walk out with out one. Lastly,a period can last for maybe a week at the most, spotting can last on and off for ever.
