Whether it is planned or not, discovering that you are pregnant can be an incredible but sometimes overwhelming experience.
It is easy to think, from the many depictions of pregnancy in the media, that life can go on pretty much as normal.
However, many people find the early weeks of pregnancy, during the first trimester, some of the most difficult, as the body undergoes some pretty drastic changes, to prepare itself for the nine months ahead.
Let’s start with some jargon-busting.
Full term pregnancy lasts around 40 weeks.And it is commonly split up into three stages, or trimesters:1
This is the period during weeks 1 to 12.
This is the period during weeks 13 to 27.
This is the period during weeks 28 until birth.
Pregnancy is worked out from a calculation from the first day of your last period and not from ovulation.You can use online due date calculators to work out which week you are in.2
Of all the first signs of pregnancy, most people usually notice the absence of a period first.
Because of the way the due date is calculated, symptoms usually do not start until you are at least 3 weeks pregnant or more.Before 6 weeks pregnant, you might experience some of the very early signs of pregnancy, including:3
You are still likely to be experiencing some or all of the early signs of pregnancy as the hormones increase in your body.
That said, some people do not experience pregnancy symptoms and still may not know they are pregnant at this point.
If you are experiencing nausea, vomiting and cravings, you might not want to think about food, but if not, this is a good time to think about dietary changes that you might need to make.For more info, check out Health Hub articles, ‘What foods should I avoid during pregnancy?’ and, ‘Why good nutrition matters during pregnancy’
You are already two months into your pregnancy at this point; just over seven to go!
You are likely to still be experiencing tiredness, nausea and all the other early signs. Look after yourself and keep going!
Gentle exercise may well help alleviate some of the symptoms, and it will certainly help your body and growing baby.
The foetus’ skeleton is changing from cartilage to bone, and most of the internal organs have formed.It can move its arms and legs now!7
Be kind to yourself and try to give yourself rest periods: you are growing a human inside you!
You are nearly done with the first trimester, but there is one symptom of pregnancy that could strike at any time: perinatal depression.If you find yourself struggling with daily tasks, low mood, feeling alone or detached, make sure you talk to your midwife or GP, who can refer you for help.9
You have done it! You have reached the end of the first trimester.Your baby is around 70-80mm long.10 You should be having your first scan this week.
Rest assured that most people start feeling much better in the second trimester, as the signs of early pregnancy subside and energy levels rise.
Not that there are not plenty of second trimester symptoms to think about…Shop Women's Health
