Pregnancy symptoms differ from mum to mum and from pregnancy to pregnancy. Some women spot early pregnancy symptoms and signs within just a week of conception but some women will get no pregnancy symptoms at all.
We've all heard stories about people giving birth without even knowing they were expecting! There is no better guarantee to tell if you're pregnant than by taking a pregnancy test and confirming it with your GP but if you think you might be pregnant, have a look at our guide to early pregnancy signs. We all know how desperate the wait can be to find out!
Early pregnancy signs
Pregnancy sign: Bleeding or 'spotting'About a week after conception, the embryo pushes itself into the wall of the uterus (or womb). This causes some light bleeding or spots of blood to appear in your knickers. You may even get stomach cramps while the embryo is moving.
What else could it be? Your period (although some women still get light periods throughout their pregnancy), changes with the Pill; such as forgetting to take it or taking it during your seven-day break, an infection, or bleeding from sex.

Pregnancy sign: Tender breastsAs early as 1-2 weeks after conception you might notice a difference in your breasts. Your nipples might be sensitive to the touch, they may be sore or they may change shape and become swollen - meaning your bra might not fit as well as normal.
What else could it be? It could be your pill or you might be due on your period - many early signs of pregnancy are similar to when you're having a period or are due on.
Pregnancy sign: Missed periodAround 4-5 weeks after conception, this is the most common pregnancy symptom, and is usually the first one you might pick up on. After the embryo has attached itself to the wall of the uterus, the wall builds itself up so the embryo is well cushioned - rather than break down and cause a period.
What else could it be? Stress, changing your contraception or excessive weight gain or loss.
Pregnancy sign: Nausea/Morning SicknessSome women complain of feeling nauseous throughout their whole pregnancy
and others manage to escape it. This well-known symptom will normally
show up between 2-8 weeks into your pregnancy.
One theory is that it is caused by an increase of the hormone
progesterone. Progesterone apparently softens the muscles in the uterus
ready for labour but it also softens the stomach muscles causing nausea
What else could it be? Food poisoning, stress, or other stomach upsets can also cause you to feel queasy.

Pregnancy sign: Fatigue/Tiredness

buses, at work and even during sex! Feeling more tired is a pregnancy
symptom that can also start as early as the first week and is because
your body is working overtime to get ready for the baby.

Pregnancy symptom: BackachesHaving a backache is a common symptom throughout your pregnancy due to
the extra weight you're carrying. But it and can also be an early sign
of pregnancy too.

you're on your period. And it's just because your body is getting ready
for the baby.
What else could it be? If you are due on your period you may get a
backache or if your suffering from physical or mental stress and tension. It could also be another back problem.

light and noise.

Pregnancy symptom: Weeing moreAbout six to eight weeks into your pregnancy you may find yourself
making a few, or even a lot of extra trips to the bathroom. It's all
because of changes in hormones, specifically an increase in
progesterone, and your body kicking out any toxins.
What else could it be? Infections make you wee a lot more as well
as if you've started drinking more water or you're on a diet. It is
also a one sign of diabetes.
Pregnancy symptom: Food cravingsHaving random food cravings
is another one of the most common symptoms. It's caused by your body
craving what it needs. Some women say they crave mud when they're
pregnant, and this may be due to a lack of iron in their blood. Others
want combinations like fish and ice-cream! this could be because of a
lack of protein and sugar.
This doesn't mean your cravings will be weird and wonderful though,
craving just cheese could mean you need more calcium, especially if it's
linked with your cramps. This can start early on and last throughout
your pregnancy. You should give into these cravings if you can, but
What else could it be? Poor diet, lack of a certain nutrient, stress, depression, or if you're due on. Craving sugar is also a sign of diabetes.

Pregnancy symptom: Feeling hot
You might not even notice the difference yourself, but if you're trying
for a baby you may have been charting your basal body temperature. This
is the temperature of your body at rest. Throughout your cycle, your
body temperature fluctuates and if it has been high for 18 days or more,
it's likely that you're pregnant. Normal temperature is 96-98°F and
when you are ovulating or pregnant, it may be around 97-99°F.
What else could it be? Your temperature is likely to rise if
you're feeling unwell with a cold or the flu. It will also rise slightly
at different stages of your cycle.
Top tip: Your basal body temperature is best taken first thing in
the morning. If you take it at the same time every day, it will make it
easy to track.
Pregnancy symptom: 'Feeling' pregnantMany women will notice that they feel uterine cramping in early
pregnancy. You could even feel period like cramps or even pain on one
side. The most common reason for this kind of cramp is that your uterus
is growing. This is normal pain and should be expected in a healthy
pregnancy. You may also feel 'full' or 'heavy' around your uterus, and
actually it's not uncommon to hear that in early pregnancy some women
describe feeling like they were about to start their period any minute.
What else could it be? If you are due on your period you may get pre-menstrual cramps.
Pregnancy symptom: Larger breastsYou might already know that one of the first pregnancy symptoms many
women experience is changes to their breast tissue. Towards the end of
the first trimester or the beginning of the second trimester you may
notice that your breasts begin to grow. This is because the tissues
inside the breast are preparing for nursing.
What else could it be? Breast tenderness and swelling can be another sign that you're expecting your period.
Pregnancy symptom: Changes in nipplesYour nipples may become larger and darker as your pregnancy
progresses. You may also notice small, goose bump or pimple like white
areas on your areola, but don't panic, these are totally normal. They're
called Montgomery's tubercules.
What else could it be? Changes in nipples should be examined as part of your regular breast check against breast cancer.
Pregnancy symptom: Low libidoIt's common to suffer from a low libido during the early stages of pregnancy.
Your breasts may be sensitive, causing you a bit of pain, plus feeling
nauseous and tired could reduce your sexual appetite. Your partner might
also be scared of hurting the baby, or of the baby 'knowing' what is
going on during sex, which of course is not true!
What else could it be? There are lots of other reasons why you could have gone off sex, from exhaustion to stress. We've outlined 10 reasons why you might have a low libido
Pregnancy symptom: Tingling nipplesSome women get a tingling feeling in their nipples as one of the very
first signs that they're pregnant. The surge in hormones in your body
causes an increased blood supply to your breasts, which causes the
What else could it be? It could just be related to your menstrual cycle, or there's a small chance a tingling feeling can be caused by an infection.
Pregnancy symptom: Shortness of breathIn early stages of pregnancy, an increase of progesterone in your body
causes you to breathe more often, which can feel like shortness of
breath. You'll also increase the amount of air you take in with each
breath. The feeling might be a bit unusual, but it's usually harmless.
What else could it be? A shortness of breath could also be caused by asthma.
