HIV is a virus that causes AIDS. It does not result from abnormal hemoglobin or abnormal hemoglobin levels.
Elevated levels of progesterone is what causes your period to stop, but hcg plays a role in that too, as it is the presence of hcg (from implanted embryo) that tells the corpus luteum to keep pumping out the progesterone after the normal luteal phase length. If there is no hcg detected the corpus luteum tapers down progesterone production after about 14 days and the endiometrial lining starts to break down when the progesterone no longer is present to support it.

Menstruation is triggered by a drop in estrogen and progesterone levels, which signals the shedding of the uterine lining. This drop in hormone levels occurs when an egg released during ovulation is not fertilized. The decrease in hormone levels causes the blood vessels in the uterus to constrict, leading to the shedding of the uterine lining, resulting in menstruation.
Progesterone
causes of abnormal pressure
decreased levels of luteinizing hormone (LH)
"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".
