Pregnancy tests are most accurate 1 week after the missed period.

Being paranoid about getting pregnant is very common is teenage relationships. Tender breasts could be from her oncoming period and the well every get nausea sometimes.

If she misses her period then you have reason to be concerned.
But even then she could just be late or happened to miss that one.

Try not to worry about it too much until you get the pregnancy test in I'd recommend early February.

If you cant afford an abortion, you could always give a good punch.

Push her down the stairs!

Also, man. Just remember to be calm. Stress can cause your girly to skip her period.

During a really stressful time in my life, my period stopped for 4 months. It's just your body's way of saying "BITCH U NEEDA CALM DOWN B4 U CAN HAVE BABY."
