Did you know that pregnancy symptoms can start right at the beginning, before you‘ve missed a period? Even when your baby is just a tiny ball of cells, the changes in your hormone levels can have a big effect on your body.
You may find the way that we date pregnancies a little bit odd. We usually start counting from the first day of your last period. When your midwife or sonographer talks about how many weeks pregnant you are, they will usually be counting from this day. The reason we do this is that your period is much easier to date than the actual conception. You can always tell when your period arrives, but unless you’re tracking your ovulation you probably don’t know exactly when it happens.
Conception happens around the time that you ovulate, but we don’t usually know exactly when it occurred because:
What all this means is that there is a 24 hour period when fertilisation can happen, but that you can have sex up to a week before this and still get pregnant. You can’t tell exactly when the egg and sperm will meet and you might not even know which day you are ovulating on. Since it’s so difficult to know when you actually conceived, no one is going to expect you to be able to tell them. Instead, your midwife or doctor will ask when your last period started. It gives us an easy date to use as the start of your pregnancy.
What makes this a little strange is that you aren’t actually pregnant at this time. Periods are a pretty obvious sign that you’re not carrying a baby. You won’t be able to conceive until you ovulate, which usually happens about 10-15 days later, depending on the length of your menstrual cycle. However, it’s much more convenient to date your pregnancy from the last period. You just have an extra two weeks that count as pregnancy before you actually get pregnant.
You will get a more accurate date for your pregnancy after your first ultrasound scan. Babies develop at a very similar rate in the early weeks, so we can tell how long you’ve been pregnant from the size and development of your baby. However, we’ll probably still use the traditional approach when talking about how long you’ve been pregnant. We’ll tell you that you’re 12 weeks pregnant even though the actual conception happened during week 2.
Clearly, you’re not going to experience any symptoms during the first two weeks that we count as the start of your pregnancy. However, you could start noticing some changes as soon as you actually conceive. What will happen during the first week after conception?
Baby has a lot of work to do during the first days after conception. When the egg is fertilised, it is still sitting in the fallopian tube. It has to make its way along this tube and into the womb, where it must implant itself in the endometrial lining in order to survive. The embryo is already growing and dividing to create new cells. Some of the cells will develop into the placenta that will feed and support the baby. Others will go on to form your baby, or in the case of identical twins, they could even end up as more than one.
The most obvious sign that you might be pregnant is a missed period, but your period won’t even be due until a couple of weeks after you conceive. During this time, you might already notice some pregnancy symptoms. Even though your baby is just a tiny ball of cells, your body is already preparing for what is to come. The hormones that would usually start to decline at the end of your cycle will instead remain high so that your womb lining stays thick and healthy. It is these pregnancy hormones that are responsible for your early symptoms. They are already starting to prepare your body for the coming months.
Possible signs of pregnancy during the first week after conception include:
These early signs of pregnancy aren’t easy to spot. In fact, they can be very easy to miss because they are so similar to pre-menstrual symptoms. You might just think that your period is coming. Even if you’re trying to get pregnant and you know exactly when you ovulated, you might still miss these signs or think that they’re due to your period. It can be a bit of a surprise to find out that you’re actually pregnant when you’ve just been thinking you’ll have to try again next month.
The earliest pregnancy tests can be taken about 6-7 days after ovulation. If you know when you were ovulating then you can take these tests about a week later. They can also be useful if you’re experiencing possible signs of pregnancy and you want to be sure. However, it’s usually better to wait until after you’ve missed a period before you try a pregnancy test as the results can be more accurate. It’s also important to check the instructions on the packet as some pregnancy tests won’t work this early.
How soon did you suspect you were pregnant?
We had received possible worrying news from our NHS anomaly scan, without much information provided or confirmation. I am so pleased that we came to The Birth Company for reassurance, as we are now extremely happy that everything is fine. Shahrzad was fantastic and went through the whole anomaly scan thoroughly, explaining everything and looking in detail at each area. Nothing was rushed and she took her time to make sure baby was in the correct position to get the best results. We can’t thank her and Dr Gibb enough for the confidence they have given us. Would highly recommend The Birth Company for all scans.
' Professional and reassuring 'Helen Campbell
The sonographer was ready as soon as I arrived, and she was extremely calming, personable and professional. The scan and blood test where efficient without feeling rushed and all very easy. These appointments can feel uneasy and make you feel anxious but I felt reassured and in professional hands the whole time
I saw Kate throughout my first pregnancy and am now doing so again with my second. She is absolutely amazing, she explains everything really clearly, and has answered all sorts of bizarre questions and worries I have had. On top of being clinically excellent she is also just the loveliest person and always a pleasure to see.Sarah Elliott
We had the harmony test with the Birth Company and had a reassurance scan with sonographer Kirsty McGarry who was absolutely lovely and really put our minds at rest. We had been scared by our NHS dating scan and left feeling like there was something wrong. We explained the situation and was treated very professionally and with good care. Also speedy appointments also as I had phone in the morning and got an appointment by afternoon. So thankful.Ashley and Tom
Really friendly, efficient service. Great experience overall. Had the Panorama. My appointment was with Kate who was absolutely fantastic. The results came really quickly. Have a comparison with private healthcare elsewhere and must say that The Birth Company was just how I would like to be treated when I pay for medical services - attentively, calmly, friendly, in a pleasant environment that doesn't look like hospital. Top marks!Anna

' Professional and friendly 'Lyndsey Dilla
When I first contacted the Birth Company I spoke to Danielle. She was fantastic. She went above & beyond to put me at easy & make the journey from Kent as stress free as possible. Every staff member that myself and my husband have come into contact with have been approachable, professional and friendly. Kate scanned me the first time and put me completely at easy. Lisa on reception is professional and very approachable. Highly recommended
' Highly recommended 'Emelie
Donald was so lovely! I was so nervous as I have a bad history and he was super quick and confirmed my baby's heartbeat as quickly as he could. He spent time showing me the baby and the anatomy and it was the best money I have ever spent! The reception girls were lovely too - considering they deal with babies day in day out they were super excited for me! Thank you so much one and all! If only I lived in London and could have all my scans with you!
