Oh dear! Have you started hibernating? Growing a tiny human can be extremely tiring, and an emotional roller coaster. Don't be surprised if you find yourself being a teensy bit moody too with all the extra hormones floating around your body. It is important to remember though that if this mood persists, it may be worth a chat with your GP.

The size of a grain of rice, your little one is also now a prize... baby SEAHORSE! Don’t worry, this change in shape is the transition to getting 1st prize in the baby show by week 40! If you were able to get a good look at your little seahorse, you would be able to see dark spots where the eyes are growing, and small buds where the arms and legs will start to grow. How amazing that in just a few short weeks, we are starting to see all the signs of a new person emerging.

Also growing this week is your little one's kidneys, liver, and lungs.

Their jaw, cheeks, and chin are also developing and little indentations on the side of its head will eventually become ears. The little bump on its face will grow into a cute little button nose in just a few short weeks! Its tiny heart is now beating away at over 110 times per minute and continues to get faster each day until it's double the speed of yours - pumping blood around its teeny tiny body.

Pregnancy hormones are getting high now, so the nausea may have reared its ugly head. Whether you ‘re being sick, or just have that horrible feeling in your throat, we're sorry to say, it may be something you need to get used to, as it can linger for a few weeks. Head here for ways to combat morning sickness. You may still have tender breasts and cramping, both of which are completely normal. If your vomiting is constant and you can't keep any food down, see your GP or doctor as it could be Hyperemesis Gravidarum.

It will also be a few weeks yet until you see a midwife, but it may be a good time to ring up your GP or community midwife and let them know your news, and get you booked in for your booking appointment at 8-weeks. Don't forget, you are now entitled to free prescriptions and dental care, so you will want to get your exemption certificate.

If you're still waiting for your body to give you some of the telltale signs of pregnancy, try to relax, because you won't be waiting much longer! By week six, your body might be experiencing any or all of the symptoms: 

Morning sickness and nausea: You might find yourself experiencing bouts of morning sickness this week, characterised by feelings of nausea or even being sick, especially in the early hours of the day. These symptoms, while unpleasant, are often a reassuring sign of a healthy pregnancy! Here are some tips for combatting morning sickness.

Food cravings: Hormonal changes can lead to unexpected food cravings this week, where you suddenly develop a strong desire for certain foods or combinations that you may not have previously liked the sound of. These cravings can range from all of the weird and wonderful sweet treats to savoury snacks. Head here for more on food cravings during pregnancy.

Tender, swollen breasts: Your breasts may feel tender and swollen as they begin to prepare for lactation. This discomfort is caused by hormonal fluctuations and increased blood flow to the breast tissue, signalling the body’s preparation for breastfeeding.

Mood swings: Hormonal changes can also influence your mood, leading to sudden shifts in emotions. You may find yourself experiencing moments of joy quickly followed by bouts of irritability or sadness. These mood swings are a normal part of pregnancy, so remember to be easy on yourself. Here’s some more advice on pregnancy emotions.

Increased need to urinate: As your uterus expands, it puts pressure on your bladder, leading to more frequent trips to the bathroom. This increased need to urinate is a common symptom in early pregnancy and may be a recurring thing throughout your pregnancy!

Metallic taste in mouth: Some people report experiencing a metallic or sour taste in their mouth, often described as similar to sucking on a coin. This sensation is believed to be caused by hormonal changes and can affect your sense of taste temporarily.

Strange dreams: Pregnancy hormones can influence the content and frequency of your dreams, leading to vivid and sometimes bizarre dreams during sleep. These strange dreams are a common occurrence and often reflect the subconscious thoughts and anxieties related to pregnancy and parenthood. Here’s a guide to pregnancy dreams.

Heartburn or indigestion: Hormonal changes during pregnancy can relax the muscles in your digestive tract, leading to symptoms like heartburn or indigestion. You may experience a burning sensation in your chest or throat after eating, especially when lying down or bending over. Here’s more on heartburn during pregnancy.

Fatigue: Your body is working hard to support the growth and development your baby, which can leave you feeling more tired than usual. It’s hard work!  

Headaches: Hormonal fluctuations and changes in blood circulation can trigger headaches during pregnancy. These headaches may vary in intensity and frequency, but they are usually manageable with rest, hydration, and gentle, pregnancy-safe painkillers.

Bloating, gas, or constipation: Changes in hormone levels can slow down digestion, leading to symptoms like bloating, gas, and constipation. You may feel discomfort or pressure in your abdomen as a result of these digestive issues, but they are generally temporary and should go away soon. Head here for more on constipation during pregnancy.

Have you heard that pregnant women should not change cat litter? It may sound strange, but it's true. Changing cat litter may put you at risk for a parasitic disease, called toxoplasmosis, which can cause pregnancy problems and serious birth defects. The solution isn't to get rid of your cat! The most important thing to do is get someone else to change the litter box (we know how much you'll miss the daily scooping). If there isn't anyone else to do it for you, wear rubber gloves while you scoop and change it. And when you are done... wash. your. hands.

Preparing For Your First Appointment

It's time to prepare for your first prenatal midwife appointment, known as the booking appointment. It will probably take place at some point between weeks 8 and 10 of pregnancy.  Ask questions and do your research to ensure you enjoy the healthiest pregnancy possible. Expect the midwife  to ask you for a lot of information, such as your personal and family history of any past conditions or problems that could threaten your pregnancy.

They will want to know when you last had your period and any pregnancy symptoms you're experiencing. They may take a urine sample, or a blood sample if procedure calls for it. 

This appointment is also an opportunity to ask your doctor which foods, activities, and medications are safe, and which are not, during pregnancy. If you have questions about your diet and weight gain, want a prescription for prenatal vitamins, or think of any other questions and concerns, ask them while you are there. If you forget and think of more afterwards, simply keep a tiny notebook in your purse and jot down each question as it comes to you, for your next appointment. If the question is urgent, call your midwife or GP. They want to help you.
