We were not trying to get pregnant, I'm a senior in high school. He pulled out quite a while before he came near ejaculating, and it happened 3 days after my period stopped. I am more than a few weeks late but have a very irregular cycle and have been under a lot of stress the last month and a half. Is there a chance of being pregnant? And I have been have light menstruational cramps but no bleeding yet.

Have you taken a test yet ?

Not yet... and I know there is a chance but is it a chance big enough to worry about?

Yes, there's a huge chance. You didn't use protection, and there's plenty of sperm in pre-ejaculate to get you pregnant. The pull out method is another way of saying "trying to conceive".

Try a pregnancy test using first morning urine, or see your doctor for a more accurate blood test. There is a definite possibility of pregnancy. Heck, even with protection there's a chance of pregnancy, you just upped the chances because you had unprotected sex.

Good luck.

I don't have any symptoms though. No tender sensitive breasts, no nausea, no tiredness, no cravings and no extra urination... But I will buy the test tomorrow and take it the day after.

The first symptom of pregnancy is a missed period.

Yeah, I know. But I have an extremely irregular cycle. Once I missed 3 months and there was NO chance of pregnancy then.

Then you will have to test. There is no way we can help you since we can't do the necessary lab work via the Internet.

I hope you take this as a learning experience.
