Cramping is the first sign of pregnancy for some women, as it is common to experience cramping when a fertilized egg makes its home in the uterine wall. This is called implantation cramping, and it can feel like your period is about to start.
Rapid growth of the uterus due to the growing foetus during first two trimesters also causes cramping.
Changing hormone levels can lead to increased gas, bloating, and constipation and this may cause mild light intermittent cramping.
Cramping is not always a sign of miscarriage.
Miscarriages often happen when there is abnormal development in an egg or embryo (usually caused by chromosomal abnormalities) and the body responds by eliminating the pregnancy. The cramping associated with miscarriage is actually caused when blood and tissue leaving the uterus irritates it, causing it to contract.
Pregnant women are also susceptible to yeast infections and urinary tract infections, either of which may cause mild cramps. Consult your doctor for appropriate treatment as soon as possible to ensure you have a healthy pregnancy.
Continuous unbearable sharp pain can be a sign of Ectopic pregnancy( Pregnancy developing outside the uterus). This needs immediate attention.
