I did have sexual intercourse with my boyfriend around the time of ovulation. 1 week later I was feeling very nauseous and that continued for a week until I started my period. My period wasn't a normal period. No cramping, not as heavy, and longer then usual. A week after I ended my period I started spotting. I was spotting for 4 days. My breast aren't sore like usual and I have some tenderness in my lower abdomen. I am using the restroom more often and I'm going to sleep earlier at night. Could I pregnant? I'm 16 years old and I'm scared. Do I got to wait until my next scheduled period to come before can take a pregnancy test?

Could you be, yes, are you, my guess perhaps not. But there is of course always chances for various infections.

And yes you wait till the next scheduled period and if it does not come, you take the test.
