Early Pregnancy: The First Trimester

Congratulations, you're pregnant! Your big moment is finally here and you must be thrilled to bits. If you're not sure how many weeks pregnant you are, our pregnancy calculator can help you work out your due date - and of course, we're here to help you too, with all of our first trimester information. Don't stress if you don't know your pregnancy dates yet, you usually have a dating scan at 5-8 weeks to confirm your due date.

Your first trimester baby

Your little one will grow from the size of a tadpole or lentil bean to the size of a ripe plum (around 5cm long) in the first trimester, graduating from an embryo to a foetus. Its heart will begin to develop and it will start to look a lot more human too ... you'll even get your first snapshot at 12 weeks pregnant.

Early pregnancy symptoms

As for your pregnancy symptoms, they're not all bad! Your period will be gone but there'll be a little fatigue and possibly moodiness ... you might notice sensitive breasts, a shrinking bladder, nausea and even the infamous morning sickness. What are you experiencing in your first trimester? Do you have any remedies or tips? Remember to add a post to share and get support from other mums, or ask our Careline of mums, midwives, dietitians and a nutritionist.

Visiting your doctor

Most importantly, visit your doctor straight away. They'll take you through a series of blood tests to check your blood group, antibody levels and all-important iron levels. They will also do blood tests called Antenatal Screening tests and will give you a referral for your first dating ultrasound.
