Here are the key symptoms to watch out for if you suspect you could be pregnant and your period hasn’t come. 

You’ve missed your period

Sometimes your period can be late, which is often due to stress and other environmental issues or may stem from a disease or medications you take. If you’re not sure if you’re pregnant or not, take a pregnancy test about 5 days after not getting your period. If you don’t track your cycle, you may find it difficult to determine if you’re late or not. Although most women have a 28-day menstrual cycle, it is entirely individual.  

Spotting or light bleeding

If you had spotting or a light flow and your period doesn’t start afterward, it may be a sign of pregnancy. An egg implants deeper into the uterine lining in the early weeks of pregnancy, and that might cause light bleeding or spotting. 

Breast discomfort

Being a symptom of PMS, breast tenderness may also be an early pregnancy sign. When you get pregnant, your body starts to change and produces more hormones. Your breasts may appear bigger and your nipples may hurt too.  

Vomiting and nausea

Morning sickness is often associated with pregnancy. It usually begins between week 2 and week 8 of pregnancy. If vomiting and nausea occur at any time of the day combined with other early pregnancy symptoms, you should take a pregnancy test.

Cramping

You may have cramps similar to menstrual ones but without bleeding. You might also have very light bleeding along with these cramps. This might be a sign of pregnancy, as when a fertilized egg implants, it may cause similar symptoms. Implantation of the fertilized egg occurs 6-10 days after ovulation, which is on day 20-24 if you have a 28-day cycle.

Changes associated with food: food cravings or aversions

A pregnant woman may have specific food cravings that are not typical for her. Food aversions are also common among pregnant women, as their sensations start to change together with their body. 

Take a pregnancy test you can get at any shop or drugstore. If you have a positive result, contact your doctor for further details.

Note: Breast discomfort, changes associated with food, vomiting and nausea accompanied by a missed period can be a reason to take a pregnancy test immediately on the first day when these symptoms occur.
