It's been three months that i've missed my period, i had sex with my boyfriend(unprotected) and i don't have infections.. am i pregnant?

Get a pregnancy test: There is no way for me to know if you are pregnant. Certainly a history of unprotected intercourse followed by missed periods in a young women is suggestive of pregnancy. You can tell for sure by doing a home pregnancy test. They are available at the pharmacy without a prescription. Many health departments and pre-natal care offices will do them for free as well. Best wishes!

Maybe: Take a home pregnancy test. Need to start prenatal care asap if positive. If negative get evaluated for secondary amenorrhea

Amenorrhea: Person in the reproductive age group, in the right clinical setting, missing periods need to have pregnancy ruled out first.
