If you suspect you are pregnant a visit to your physician will be necessary to confirm the good news. Most new moms-to-be are so excited when the at home pregnancy test is positive that they have a million things running through their head. Learning how to discover the conception date of a baby before your doctor is pretty easy once you know the method.
How Did I Conceive So Quickly
Believe it or not, it is possible to get pregnant before ovulation begins. This is because sperm can remain alive in a female’s reproductive system for days. If intercourse were to occur during this time, there is a chance of a woman getting pregnant. Because each woman is different, it is not possible to pinpoint how many days each month she ovulates, but it has been noted that there are between three to six days each month in which a woman can get pregnant.
Calculating Conception Dates
Normally the first question your physician will ask is when was your last menstrual period? They take that date to determine a delivery date for the baby. This date is often calculated using a chart, but a sonogram is often used to get a more accurate date, which is determined by the size of the fetus, stages of development, etc. There are a few other methods used to get a more precise date, but they do require some basic math skills.
Counting Backwards Method
First make a note of your previous period. Next, the date you would have gotten a period had you not become pregnant.
If you have a normal 28 day cycle, counting back 14 days from your first missed period will give you the possible date you conceived. For example, if a period should have come on May 20th, you should subtract 14 days from the 20th. This gives you a May 6th date, the likely date pregnancy occurred.
The way this works is simple. You count back 14 days from the date you expected a period.
For women with cycles longer than 28 days a slightly different method is used. Add 14 days to the first day of your prior period or subtract 14 days from the date of your first missed period. This method is not as precise if cycles vary in length, but it will give you a general idea of when you conceived.
For example, if you were expecting to start your period on January 20th, adding 14 days will give you a date of January 3rd. If your first missed period was February 20th, subtracting 14 days would be January 6th. It is safe to assume that you conceived somewhere between January 3rd and January 6th.
Naegles Rule is a formula that calculates your estimated due date based on the average pregnancy lasting 280 days from the your last period. This is a little more complicated but not too difficult to calculate. Add 7 days to the first day of your previous menstrual period, subtract three months, then add one year. This gives you the estimated due date. Now subtract 38 weeks or 266 days from your expected date of delivery to get the date your baby was conceived.
No doctor or method can tell you an exact date, but give you a general idea of when your baby was conceived. What is most important is that you have a healthy pregnancy and delivering a healthy baby.
