please i want to know if it is possible to have a sexual intercourse with a woman on the on the 1 to 5th of october 2009 and the child is born on the in the 18th of june 2010. because there is a doubt if this is my child because by my calculation the birth was less than 9 months.
The expected due date of the delivery is calculated by formula :
DD = LMP + 9 months + 7 days.
Egg release takes place about 14 days after (in fact 14 days before the next expected menses) the LMP. So the date from solitary intercourse causing pregnancy will have to be modified by two weeks.
The delivery can take place any times 3 weeks prior to 1 week after the DD.
The baby was born on 18th June, 2010 (and if this was full term), the date of her LMP would be 11 September 2019 and any intercourse around end of September to early October 2009 can cause pregnancy.
However, this is all rough calculation. Before challenging the paternity of the child, you should go for DNA test.
Sometime birth of child can occur at eight month also .... Its not exact date that is calculated will be your child birth date. ... It varies according to many causes ....
Here if you have doubt regarding paternity of child than molecular methods for DNA analysis has to be done which is confirmatory for that .... Ex PCR ...
Take care ...

Hallow Dear, By and large, the pregnancy is of 280 days. The expected due date of the delivery is calculated by formula : DD = LMP + 9 months + 7 days. Egg release takes place about 14 days after (in fact 14 days before the next expected menses) the LMP. So the date from solitary intercourse causing pregnancy will have to be modified by two weeks. The delivery can take place any times 3 weeks prior to 1 week after the DD. The baby was born on 18th June, 2010 (and if this was full term), the date of her LMP would be 11 September 2019 and any intercourse around end of September to early October 2009 can cause pregnancy. However, this is all rough calculation. Before challenging the paternity of the child, you should go for DNA test. I hope this helps you. Dr. Nishikant Shrotri
