Every pregnancy is different, but there are still signs and symptoms that you can look out for that will indicate whether or not you have conceived. Not everyone will have all of the symptoms, and if you're concerned about anything, it's best to talk to a GP or midwife.
If you have a regular monthly menstrual cycle, the early and most obvious sign of pregnancy is a missed period. In the first few weeks of pregnancy, you may have a bleed which is similar to a very light period, with some spotting, or only losing a small amount of blood, which is called implantation bleeding.
Another symptom of pregnancy is feeling sick. This is commonly known as "morning sickness", but vomiting and morning sickness can happen at any time of the day or night.
Typically symptoms begin when you're approximately four to six weeks pregnant. You should see a GP if you're being sick constantly and can't keep anything down, because you may have hyperemesis gravidarum, which is a serious condition in pregnancy that causes extreme vomiting and requires treatment.
It's also common to feel tired or even exhausted during pregnancy, especially during the initial 12 weeks. Hormonal changes in your body mean you can feel tired, emotional, sick, and upset.
You breasts may also become visibly larger in early pregnancy, and feel tender, especially before your period. They may feel tingly, have more visible veins or darker, more prominent nipples.
Another sign of pregnancy is the need to pee more often than usual, especially during the night. You may also experience constipation or have more vaginal discharge, without any soreness or irritation.
During early pregnancy, you may find that you no longer enjoy some foods or drinks which you used to like. You might experience a strange taste in your mouth, which some people describe as metallic.
You could also crave new foods, lose interest in certain foods or drinks you used to enjoy, like tea, coffee, or fatty food. You might lose interest in smoking and be more sensitive to certain smells, like the smell of cooking or food.
If you do a home pregnancy test, a positive test result is almost certainly correct, as long as you have followed the instructions correctly. A negative result is less reliable.
If you get a negative result and still think you may be pregnant, wait a week and try again. If you're pregnant, use the pregnancy due date calculator to work out when your baby's due.
