If you are curious about the day your baby was conceived, more than likely you have come across several calculators where instant results are given. These are somewhat accurate, but for a more precise method learn how to discover the conception date of a baby in this article.
Conception and Ovulation
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
Upon visiting your physician after suspecting you are pregnant the first question is, when was your last period? Next they pull out their little chart and give you an estimated due date. This is only an estimate and not an exact science to calculating the due date. The same holds true for other charts and calculators. Because every women has different ovulation dates, there is no way to get an conception date; however, there are methods that provide a more accurate date.
Backwards Conception Calculation
Write down the first day of previous period. Now write down the date you were expecting your next period, which did not occur because you were pregnant.
If you have a 28 day cycle, you will subtract 14 days from the first date you had your previous period. If you were expecting a period to start on June 30th, subtracting 14 days would give you the most probably date of conception. This date would be June 16th.
Basically, you count backwards 14 days from the date you expected to start your previous 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.
There are two examples of these methods. With missed period on May 15th, adding 14 days gives you a May 29th date. With the date of the last period June 15th, subtracting 14 days brings you to June 1st. This essentially means pregnancy occurred between May 29th and June 1st.
Another formula used is based on an average pregnancy lasting 38 weeks or 280 days. This is from the time of the last period. First you add seven days, subtract three months, then add one year. Now you have the estimate date of delivery or due date. Next, subtract 266 days or 38 weeks and you will get the estimated date you got pregnant.
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.
