Well, are you trying to prevent or make pregnancy? Having sex intercourse during a fertile day does not always produce a pregnancy, which also depends on the viability of the sperm and woman egg, the receptivity of the uterus and other factors that vary widely among couples.http://www.trcb.com/en-Us60Sat, 26 May 2012 07:48:33 ESTCopyright 2012 Thomas Karanja, TRCB.com All Right Reservedhttp://www.trcb.com/women-interests/women-interests/woman-safe-and-unsafe-days-for-sex-or-pregnancy-21251.htm<p>Well, are you trying to prevent or make pregnancy? Having sexintercourse during a fertile day does not always produce a pregnancy, whichalso depends on the viability of the sperm and woman egg, the receptivity ofthe uterus and other factors that vary widely among couples.</p><p>As far as a cycle goes, ovulation is supposed to occur approximately 2 weeksafter the menstrual cycle. A menstrual cycle is about 1 week long so you wouldassume that ovulation occurs another week after that. Keep in mind that everywoman's cycle is different; most of us have our periods every 28 - 32days&nbsp;</p><p>The fertile time is roughly 7 days before ovulation, the dayof ovulation and 3 days after; this is therefore one-third of your whole cycle<br /><br /> Generally speaking (because none of this is 100%) the weekbefore and the first few days of your cycle should be safest<br /><br /> It's therefore considered safe to have unprotected sex during menstruationand a few days after it, before noting fertile cervical mucus which are clear, Itis also safe 2-3 days after ovulation, when mucus decreases in volume andbecomes cloudy and tacky. As explained below:<br /><br /> Early in your monthly cycle, several days AFTER women period ends, estrogen(female hormone) levels rise which triggers the release of a cervical mucous(vaginal discharge). Throughout our cycle, this mucus increases in volume,changes from clear to a milky white as well as changes in texture. You ARE mostfertile, when your mucus/virginal discharge is clear, slippery, and stretchy -this mucus resembles raw egg whites. In other words you are ovulating and mostlikely would get pregnant. You see it is this clear mucus/vaginal dischargethat allow the sperm to enter the uterus and swim toward the fallopian tubes insearch of an egg to fertilize. Woman periods arrive to shed the unfertilizedegg and uterine lining/blood. Periods allow woman body to shed the lining ofthe uterus (what is seen as blood/woman period).</p><p>Woman body/uterus did not needthe nutrients/blood that lined the uterus because no egg was fertilizedtherefore their body rids itself of the egg's home(ovary). After ovulationthere is an increase in progesterone (another hormone) which makes our virginalmucus/vaginal discharge scant in supply, and the mucus changes from clear to amilky white appearance, the discharge is also thicker with a pasty feel. Thistype of mucus/vaginal discharge blocks the sperm's path through the cervix tothe fallopian tubes. Knowing all of this information and if vigilant practicedthe mucus method of monitoring the most fertile time of the month is only about85% effective to prevent a pregnancy. Use of condoms and other contraceptives canprevent pregnancy too.<br /><br /> Incase of accidents; see your doctor for emergencypills/morning after.
