An unplanned pregnancy can bring emotional, practical, financial, and medical considerations. Getting accurate information early can help a person understand their options and decide what to do next.
If you think you may have been exposed to an STI, a healthcare professional can advise you about the appropriate tests and when they should be taken.
For people who can become pregnant, vaginal sex can result in pregnancy if sperm reaches an egg.
Pregnancy can occur even when intercourse happens only once. The likelihood depends on factors such as timing in the menstrual cycle, fertility, and whether contraception was used.
Relying on assumptions about a person’s fertile days can be unreliable because ovulation does not always occur on the same day every month.
