What to expect during your first, second and third trimester.
How many weeks are you pregnant for?
40 weeks is the usual estimate, and how your due date will be calculated. Remember this is only a guide, and a typical pregnancy can last from 37 to 42 weeks. To start counting your pregnancy in weeks you need to start from the first day of your most recent period.
These early stages cover the first 3 months of your pregnancy, starting from the first day of your last period, through to week 12.
Signs that you are pregnant
First symptoms that you are pregnant can include feeling tired or nauseous - but these aren't always experienced and could just be a bug you've picked up.
For most women the first thing they notice is that their period doesn't arrive - but again this doesn't necessarily mean you're pregnant. Taking a pregnancy test is the most reliable way of finding out for sure.
If you think you might be pregnant, book an appointment with your GP or a maternity service to start your pregnancy care.
What to expect in weeks 13-28
You're a third of the way through your pregnancy, and hopefully some of the nausea and other symptoms you may have experienced in your first trimester will have subsided (phew!).
If you have an urge to wee...a lot...don't worry. It's totally normal as your bladder makes room for your growing womb. If it starts to hurt when you pee, pop along to your GP to get checked over.
There may be a few more visible signs that you're pregnant too with a growing baby bump - you might feel those first kicks too. You'll have the option to find out the sex of your baby at your second routine sonogram (at around 18-21 weeks). Have you planned how you're going to surprise friends and family yet?
What to expect in weeks 29-40
In around 12 weeks you'll be meeting your baby! This last stretch can take a toll on your body and you might feel uncomfortable and irritable, but you're in the home stretch.
Baby will gain around half of their birth weight in these last three months, and is doing impressive things like opening and closing their eyes and controlling their own body temperature.
With all this growth, you might experience shortness of breath (regular rests recommended) as well as swollen feet and ankles, and perhaps even some 'practice contractions' (Braxton Hicks is the technical term). Start to slow down in the last few weeks, ticking off those last few pre-birth preparations before little one arrives.
