​​In order for pregnancy to happen, sperm needs to meet up with an egg. Pregnancy officially starts when a fertilized egg implants in the lining of the uterus. It takes up to 2-3 weeks after sex for pregnancy to happen.

​

Many people notice symptoms early in their pregnancy, but others may not have any symptoms at all.

Common signs and symptoms of pregnancy can include:

​

• Missed period

• Swollen or tender breasts

• Nausea and/or vomiting

• Feeling tired

• Bloating

• Constipation

• Peeing more often than usual

​

Some early pregnancy symptoms can sometimes feel like other common conditions (like PMS). So the only way to know for sure if you’re pregnant is to take a pregnancy test. You can either take a home pregnancy test (the kind you buy at the drug or grocery store), or get a pregnancy test at your doctor’s office or local teen clinic/Planned Parenthood Health Center.
