Am 17 yr old and had cancer when i was 15 years Is there a chance can be pregnant have unprotected sex the past 3 months nothing yet. some one help me understand?

There is a chance that you could be pregnant. Sperm can live inside a woman's body for up to 5 days, so even if you had unprotected sex three months ago, there is still a possibility that you could become pregnant. If you are concerned about being pregnant, you should take a pregnancy test. Pregnancy tests are available at most drug stores and can be taken at home. If you are pregnant, it is important to see a doctor as soon as possible to discuss your options and to get the care you need.
