Your Pregnancy Week by Week
Whether this is your first pregnancy or your fourth there is still a lot to discover. Pregnancy is usually a delightful period of a woman’s life but it’s not without its drawbacks and worry.
Using our 14 years of experience in the prenatal industry, we’ve brought together a detailed guide so you can follow your pregnancy week by week.
We understand that you have concerns and often need reassurance that your pregnancy is going to plan. We also understand your desire to meet your new baby, even when they are still inside your tummy.
That’s why we’ve broken down our pregnancy week by week guide into easy to digest sections, these sections include:
Your Baby
We’ve brought you information about how your baby is growing in your womb along with letting you into the secrets of their development. With our guide you’ll know when your baby develops fingers and toes along with certain aspects of their unique personality.
Your Body and Symptoms
Your body undergoes huge change in pregnancy and if this is your first child you may find the changes a little strange. Many women often worry that they are displaying symptoms that may not be normal too. This section aims to answer general questions about how your body changes week to week, what’s normal and how to adapt to cope with your growing frame.
We also let you know about common symptoms you may be experiencing. Remedies to help with different stages of pregnancy symptoms, such as morning sickness and backache, and ideas on how to stay healthy during your pregnancy.
Symptoms to Watch Out For
Unfortunately not every pregnancy runs smoothly and when you display symptoms such as bleeding during pregnancy you can become very stressed and anxious. Our section lets you know of symptoms you should watch out for and when you should call your Doctor for help.
Your Care on the NHS
The NHS have a fairly similar care strategy for all pregnant women, unless complications arise, in which case the strategy changes. We let you know of the care you should be receiving week by week from your NHS provider, your midwife and your GP.
Other Care Available
Sometimes NHS care isn’t enough. Many women like to book extra scans to see their growing baby or receive additional support and help. We let you know of private care options available either as a one off service or throughout your whole pregnancy.
