- Persistent cramping, especially in early pregnancy, with or without bleeding.
- Severe pain on one side, with or without bleeding. This may indicate an ectopic pregnancy, where the embryo implants outside the womb, usually in one of the fallopian tubes.
- In later pregnancy, abdominal pain with bleeding may be caused by the placenta coming away from the uterus wall, a serious condition that requires immediate medical attention.
- Pain high under your ribs. This can be a sign of pre-eclampsia and should always be checked out by a doctor.
- In early pregnancy especially, call a doctor if you experience unusual dizziness or weakness. It can be a symptom of ectopic pregnancy, in which the embryo grows outside the womb in the fallopian tube. If left untreated, it can cause the tube to burst.
- In later pregnancy, dizziness can be a symptom of pre-eclampsia.
- Dizziness accompanied by bleeding and/or abdominal cramps could be a sign that the placenta is separating from the wall of the uterus. You should seek help urgently.
- In the first trimester, bleeding can sometimes but not always be a sign of miscarriage.
- Bleeding later in pregnancy can occur if the placenta is lying across the cervix, a condition known as placenta praevia. This condition must be closely monitored.
- In late pregnancy, bleeding with abdominal pain can be a sign that the placenta is coming away from the uterus. This is very serious and needs prompt medical attention.
- At the end of pregnancy, a blood-stained discharge could be a 'show' a sign your cervix is preparing for labour.
- If you experience vaginal discharge that smells offensive and you're sore or itchy, you may have a fungal or a bacterial infection. It's important to get this treated as soon as possible, so see a doctor.
- A gush or steady leakage of fluid from your vagina may mean the bag of waters around your baby has ruptured. If you're less than 37 weeks pregnant you'll need to be monitored.
- Occasionally an exaggerated form of pregnancy sickness, known as hyperemesis gravidarum, develops. Treatment may be necessary to prevent dehydration and malnutrition.
- Very rarely, vomiting that develops in the last three months and is accompanied by pain in the upper abdomen can be a symptom of pre-eclampsia. Seek urgent medical help.
