How soon will I know?
Unless you have a test beforehand, the first indication that you may be pregnant is when your periods stop.
The first signs of pregnancy
Periods are sometimes late and just missing one doesn't necessarily mean you are pregnant. But if your breasts feel swollen and you feel nauseous particularly first thing in the morning, you would be advised to have a test.
When can I take a pregnancy test?
You can take the test any time you think you may be pregnant. However, you should know that conception takes place at the time of your ovulation - normally on the 14th day of your cycle (day one being the first day of your period). So if you take a pregnancy test on the day after sex, don't think a negative result means you're not pregnant; conception may take place a few days later!
When will baby be born?
The average pregnancy lasts 40 weeks and the starting point is day one of your last period - even though you hadn't conceived then! You'll find a calculator on another page which will give you a fairly accurate estimate when baby will arrive, and you will get another, probably more accurate, estimate when you have your ultrasound scan.
