I had protected sex on February 12 and used the pull out method with a condom on to be safe. Had a little "fun" on Feb 14th (foreplay, etc.) and she wanted to have sex. She stuck it in her and I pulled out about 3-5 seconds later because I didn't have a condom and didn't feel comfortable having sex without a condom, especially at a young age. She has been repeatedly saying stuff like "I think I'm pregnant." or "What if I am pregnant?" and saying stuff like that.. She was supposed to start her period yesterday (February 22) and hasn't started yet, not even today. She has been either really happy, depressingly sad, or aggressively angry. She's been picking fights with me and having mood swings the past few days. Is she pregnant or is she starting her period soon?
