Im 17 years old, I've had unprotected sex and we also tried the pull out method. I'm not sure if its an irregular period but I missed my period on June and July. I have no pregnant symptoms, just dizziness and craving. I had spotting about a week ago. I took a HPT on Monday July 23 and it was negative. My next period is suppose to be today July 25 and I haven't gotten nothing, no cramps or whatnot. What can this be? Can it be stress? Should I wait and take another test later on?

Take a pregnancy test with first morning urine. Missing two periods usually says pregnancy. The pull out method doesn't work at all, there's plenty of sperm in "pre-come" to get you pregnant.

You've also posted this question like 3 times already. 40 days late, maybe you should go see a doctor, he can tell you for certain.
