First trimester of pregnancy

First trimester pregnancy weeks 6-12

Your first trimester begins the day you conceive – or, as far as you're concerned, the moment you get that positive sign on the pregnancy test – and lasts until week twelve. Because it can take a while to start noticing any pregnancy symptoms, and to work out just how far along you are, most things worth mentioning are from week six onwards. There's still plenty of time to get used to the news and think about what's to come in the next nine months, but at this stage you're bound to have lots more questions than answers.
