she already gave birth just want to confirm if its normal to gave birth on that date with those given information for a first born
Do you mean she is 31 and you wonder if there is a known amount of time it would take to get her pregnant? There is no set length of time. If she does not get pregnant after two years of having unprotected sex on a regular basis during her fertile times of the month, a doctor would be willing to do a workup to see if there are any issues at play that would lead to infertility, but only a year of trying is not seen by doctors as unusual.
Is she pregnant? Can't really give a due date til you know if she's pregnant or not...
Are you saying you've been having sex for a year and she's not pregnant yet?
