Hi, I'm 18 years old and this is the very first time this has ever happened to me. My fiancé and I have been having unprotected sex for about 6 months now and nothing has ever happened. My perios is usually pretty heavy but lately I been having extremely light period.. I have some cramps here and there but not as bad as when I usually get my "real period", my breasts have been very sore also. Do you think this could be an early pregnancy sign? Should I go see a doctor?

If you are having unprotected sex there is a good chance that you could be pregnant,however no one can say online for certanity if you are or not.

I suggest a visit to your doctor.
