While late are skipped periods are common missing more than one or two can indicate health problems. See your doctor. He/She will still give you a pregnancy test, but after it comes back negative they can perform other tests to determine what is wrong.
If you have had sexual intercourse involving your vagina, there is a possibility, and you should take a test.
The estrous cycle comprises the recurring physiologic changes that are induced by reproductive hormones in most mammalian placental females. Humans and great apes undergo a menstrual cycle instead. Estrous cycles start after puberty in sexually mature females and are interrupted by anestrous phases. Typically estrous cycles continue until death. Some animals may display bloody vaginal discharge, often mistaken for menstruation. Mammals share the same reproductive system, including the regulatory hypothalamic system that releases gonadotropin releasing hormone in pulses, the pituitary that secretes follicle stimulating hormone and luteinizing hormone, and the sex hormones including estrogens and progesterone. However, species vary significantly in the detailed functioning. One difference is that animals that have estrous cycles reabsorb the endometrium if conception does not occur during that cycle. Animals that have menstrual cycles shed the endometrium through menstruation instead. Another difference is sexual activity. In species with estrous cycles, females are generally only sexually active during the estrous phase of their cycle (see below for an explanation of the different phases in an estrous cycle). This is also referred to as being "in heat." In contrast, females of species with menstrual cycles can be sexually active at any time in their cycle, even when they are not about to ovulate. Humans, unlike some other species, do not have any obvious external signs to signal receptivity at ovulation (concealed ovulation). Research has shown however, that women tend to have more sexual thoughts and are most prone to sexual activity right before ovulation. Hope this helps! Best of Luck!
reproduction
During menstrual period
this is sexual harrassment
haploid, diploid, and alternation of generations
No, having multiple sexual partners has no impact on the menstrual cycle at all.The menstrual cycle is the reproductive cycle, it is controlled by hormonal changes within the reproductive organs and so sex does not change the cycle (unless the person falls pregnant). The menstrual cycle can't tell how many sexual partners a person has, nor would there be any reason for the menstrual cycle to change if a person has multiple sexual partners.
how many month in a year is a male pet rabbit more sexual active
