Pregnancy is the time when a baby develops in the womb. A period is the time in a woman's monthly cycle in which she bleeds and sheds uterine lining. Early pregnancy symptoms may be confused with period symptoms because they can be similar.

It is easy to confuse early pregnancy and the symptoms of your menstrual cycle, which is usually referred to as your period. There are many similarities in these symptoms. Both may be uncomfortable or painful.

It may be difficult to know if you’re pregnant because early pregnancy symptoms are so similar to period symptoms. If you were not planning a pregnancy, you may go months without knowing that you’re pregnant. This is why it’s helpful to know the differences and similarities of early pregnancy and period symptoms. 

What is pregnancy?

Pregnancy is the period of time when your baby develops in your womb. Pregnancy lasts about 40 weeks, or about 9 months. It is broken up into three trimesters

There are different expectations for each trimester. Some people may not know that they’re pregnant during their first trimesters. 

What is a period?

Menstruation is when a woman bleeds due to the periodic, usually monthly, shedding of her uterine wall lining. Menstrual blood and tissue discharge from the cervix in your uterus and passes through your vagina

Your uterine lining thickens each month to prepare for a pregnancy. When that doesn’t happen, the lining is shed. Women’s cycles and flows are all unique. 

Signs of early pregnancy and period symptoms

Most period cycles tend to have a heavier blood flow than the spotting of blood that can occur in early pregnancy. However, there are other symptoms that can be the same for both early pregnancy and a period.

Diagnosing early pregnancy and periods

You may have an easier time determining which symptoms you’re having if you start by tracking your symptoms on a calendar each month. This will help you determine how you’re feeling and notice any patterns you may have including PMS. 

Your doctor will ask you several questions to rule out possible problems. They may want to know about your eating habits, exercise habits, work, and family history

Keeping track of your symptoms will also help you know if you’ve missed a period. 

Only a licensed healthcare professional can diagnose pregnancy. If your doctor suspects you may be pregnant, they will order a blood test and ultrasound scan to confirm. 

Treatments for early pregnancy and periods

Both early pregnancy and period symptoms are easily managed on your own. 

Once you’ve found out that you are pregnant, you should learn what to avoid and what to do to help your baby have proper development. Before you try any home remedies, check with your doctor first to make sure they are safe for you and your baby. 

To ease pregnancy symptoms, eat healthfully, drink plenty of fluids, and take your prenatal vitamins. Reduce your stress with yoga and meditation. If these remedies do not work, contact your doctor about safe medications to take. 

If you have gotten your period and are not pregnant, there are remedies you can try at home to care for your PMS symptoms. These include: 

  • Exercising regularly through the month
  • Eating healthy foods consistently
  • Getting enough sleep
  • Managing stress through yoga and mediation
  • No smoking

There is no cure for PMS symptoms or early pregnancy symptoms, but you can manage your pain. Try home remedies to relieve your discomfort.
