It occurs at any time

Cows don't experience a menstrual cyle at all. Only humans and a few other animals like primates menstruate.

It's unusual to have your period on the same numerical date of the month when you're on birth control pills. Since the pill goes on a cycle of 28 days, and a month has anywhere from 28 to 21 days, you'd normally have your period every 28 days, which means if you had it on the 21st of July, you'd expect it on the 18th of August, the 15th of september, the 13th of October, the 10th of November. There is no reason to expect your period to follow the calendar on or off the pill, since neither your ovaries nor the pill know that "Thirty days hath September..." etc.

I am going threw the same thing cramps and nausia .. I get a blood test tomorrow it is only 6 days after ovulation --- YES!

The pituitary gland.

Both in females and males, regulates LH/FSH which in turn triggers ovulation and in the male, spermatogenesis. However in the female, there's a huge monthly peak whereas in the male, the peaks are daily, but at much lower levels.

During ovulation multiple eggs can be released but eggs will only live around 24 hours, even with multiple eggs produced at most there is only a viable egg present for 48 hours.

This is one of the great things about reproduction, around a week leading up to ovulation the cervix produces mucus that allow the sperm to swim up where they can swim into the fallopian tubes and then hibernate until the woman ovulates, hormonal signals then tell the sperm to 'wake up'. Thus rather than there only being one day when a couple can have sex to get pregnant, there are up to 10 fertile days.

Hello, Unfortunately a Saliva Ovulation test cannot detect pregnancy because HCG will not be found in saliva. HCG is only detected in blood or urine. ------------------------------------------------------------ Please note this is advice only & is not to be used in place of a Medical experts. ------------------------------------------------------------

Women usually ovulate 14 days before the first day of bleeding... middle of their cycle. if you are an irregular cycle I recommend using the Ovulation Predictors found in stores or here on the net."ovulation calculator-is what I use through a site by 'www.Google.com' If you don't know how to calculate your fertile days consult your doctor, maybe he/she can help you! good luck hope this helped~

Yes, this is normal. It could be pregnancy related or due to your period arriving. If your period fails to arrive, then perform a home pregnancy test - HPT.

The hormones produced by the pregnancy prevent an egg being released.

On a 28 day cycle, day 14 will be your ovulation period. Ovulation window is 3 days. You can purchase a ovulation predictor kit from your Pharmacist & see when your Ovulating. Write the dates down in a record & on a regular cycle you should notic ovulation occurs around the same day every month. Symptoms of ovulation are: * Increase in vaginal discharge. * Egg-white vaginal discharge. * Mild abdominal cramping or twinges (occurs only in some individuals).

When body fat is lacking, estrogen production may be altered enough to cause late ovulation. Often, a delayed period is the only sign a woman will have that ovulation has occurred later than usual.

Fasting is not starvation, but rather the body's burning of stored energy. Starvation occurs when the body no longer has any stored energy and begins using essential tissues such as organs for an energy source.

Some women have a slight amount of discharge when they are ovulating.

Ovulation is always 16-18 days after the first day of your cycle. For example, if you have began your cycle on Monday, February 11; begain to count that day until you have reached the sixteenth or eighteenth day.

This is not necessarily true for everyone though. Some women, like myself, ovulate late.

Sperm typically live for 72 hrs.

The average is 14 days before your next expected period, so in your case around day 17 of your cycle!

The time between having a period ...( Two weeks After Or Two weeks Before!!)

Hi 12-24 hours. Here's a really useful web page about ovulation and fertility. Copy this complete link and paste it into your browser's address window. http://www.americanpregnancy.org/gettingpregnant/ovulationfaq.htm Phil

Sperm can live in the female body for up to seven days, on average 3 - 4 days, so if you have sex before you ovulate, but then ovulate a few days later, the sperm may be alive and result in pregnancy.

Menstrual cycle consists of two phase: follicular phase‎ and luteal phase. Luteal phase starts the day after ovulation and ends the day before you get your menstruation. Many women have a luteal phase that is about 14 days long, but it can range from 10-16 days. So, if you have 28 day cycle and length of luteal phase 14 days - ovulation occurs on the 14 day of the cycle. If you have 31 day cycle, and the length of luteal phase 14 days - ovulation takes place on the 17 day. If you have 31 day cycle but the length of luteal phase 16 days - ovulation occurs on the 15 day. It's more easy to use calendar to predict ovulation, e.g. i use this one www.ladys-calendar.com
