There are different formulas.  The easiest one is: (LMP-7 days)-3 months.  LMP is last menstral period.  The date is at best an estimate of when you conceived and rather than add the number of months they just subtract to bring the pregnancy to 9 months.

Your due date is just an estimate of when baby will arrive. It's normal to be early or late anywhere around the due date. Very rarely does a woman give birth on her due date. As long as you and baby are healthy, I wouldn't worry about it. Congratulations!

5 to 6 weeks from the last menstural period.Foetal heart movements can be seen by the seventh week.

The due date is only an estimated time of arrival.  The baby could come 2 weeks before or 2 weeks after the due date.  At this point of the pregnancy you are supposed to see your OBGYN once a week so that he can check the baby and see if you are beginning to dilate.  If you start experiencing true labor where the contractions are becoming closer together and more intense or if your water breaks, then you go to the hospital.  You would go to the area in your hospital where the babies are delivered, Labor and Delivery.  I don't know why you go to the emergency room unless the Labor and Delivery was closed or if you felt that your baby coming was suddenly an emergency situation.  If you think you have reached true labor, then call Labor and Delivery and they will ask some questions to determine if it is true labor or Braxton Hicks (false labor).  Again, if the water breaks, then it is time to go to Labor and Delivery.

I think that depends on who you talk to.  Some people believe that you're human at the moment of conception, some believe that you're not human until the second trimester.

The 11th day from the start of your period.  So, if your period started on the 8th, then the 19th would be the day!  Some can also feel that they are ovulating by that little pain/ache/pinch in their side(s).  (Word to the wise - try it the 9th after your period through the 13th day if you guys can!)

Most people usually are pregnant within six months, a good portion more by the end of the first year.  No need to worry yet.  It may be more difficult to get pregnant because your periods are irregular, so predicting ovaulation can be hard. There are ways you can detect it, though.  You can start by taking your temp every morning when you first get up.  About 10 days after your last period started, you should begin to ovulate.  When this happens your basal temp will be slightly elevated.\nThere are dietary changes you can make as well to increase your chances of becoming pregnant.  FIrst and foremost, make sure you are taking a prenatal vitmain if you aren't already.  Decrease your sugar intake.  Excess sugar has been linked to fertility difficulties.  Eating foods high in zinc have been linked to reproductive health as well.\nI wish you lots of luck and hope there is a baby in your near future!!

No, if you're not a minor (requiring parental notification), second-trimester abortions are not restricted.\n\nhttp://www.medicalnewstoday.com/medicalnews.php?newsid=39237\n\nhttp://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=3353873&dopt=Abstract

If you're talking about trying to conceive, it's not about when in the month you can have one, it's about your monthy cycle.  It's best to start trying 2 weeks after the first day of your cycle.  That puts you right in the middle of the "off season".  If this doesn't work, try purchasing a fertility monitor at your local drugstore in the woman's care isle.  See your doctor for more details.

~~Fetal Development~~\nDevelopment of the Embryo and Fetus\n\nOverview\n\n* Did You Know?\nPregnancy is counted from the first day of the mother's last period. This means that at conception, the unborn child is already considered two weeks old.1 \nFirst Trimester \n \nWeek 2* Conception is the moment at which the sperm penetrates the ovum. Once fertilized it is called a zygote, until it reaches the uterus 3-4 days later. \n1st trimester photos\n \nWeek 4 The embryo may float freely in the uterus for about 48 hours before implanting. Upon implantation, complex connections between the mother and embryo develop to form the placenta. \nWeek 6 The embryo is about 1/5 of an inch in length. A primitive heart is beating. Head, mouth, liver, and intestines begin to take shape. \nWeek 10 The embryo is now about 1 inch in length. Facial features, limbs, hands feet fingers and toes become apparent. The nervous system is responsive and many of the internal organs begin to function. \nSecond Trimester\n  \nWeek 14 The fetus is now 3 inches long and weighs almost an ounce. The muscles begin to develop and sex organs form. Eyelids, fingernails, and toenails also form. The child's spontaneous movements can be observed. \n2nd trimester photos  \nWeek 18 The fetus is now about 5 inches long. The child blinks, grasps, and moves her mouth. Hair grows on the head and body. \nWeek 22 The fetus now weighs approximately 1/2 a pound and spans about 10 inches from head to toe. Sweat glands develop, and the external skin has turned from transparent to opaque. \nThird Trimester \n \nWeek 26 The fetus can now inhale, exhale and even cry. Eyes have completely formed, and the tongue has developed taste buds. Under intensive medical care the fetus has a over a 50% chance of surviving outside the womb. \n3rd trimester photos \nWeek 30 The fetus is usually capable of living outside the womb and would be considered premature at birth. \nWeek 40 This marks the end of the normal gestational period. The child is now ready to live in outside of his mother's womb.

Changes in You\nYou might actually start realizing some changes 4 weeks pregnant. Some women start to feel a little bit tired during pregnancy at 4 weeks, which is not surprise given the remarkable work your body is performing to support your new baby! Many women liken the symptoms they are feeling during this stage to those they feel around the time of menstruation. You may in fact experience during pregnancy at 4 weeks nothing other than some menstrual symptoms, including a bit of nausea and even some cramping. Believe it or not, some women cramp very badly during this time and are absolutely positive that they are about to get their period, only to find that they are actually pregnant a week or so later.

Dont listen to vish or slick_chique. It is possible.  I had my period during the first 2 months I was pregnant. Both times I was pregnant actually. Your best bet would be to take a pregnancy test, or go to the doc to find out for sure.
