All it takes is a drop, so withdrawal not a good method
Yup, you sure could be. Time to get a blood test from the doc. : )
You very well could be pregnant. Although he pulls out every time before ejaculation, men do excrete sperm even before ejaculation. When I got pregnant with my daughter it took a month before a pregnancy test came out positive. I had cramping, and pain in my lower back around my hips. I would take another test in a week. If your period still hasn't started, and this test is negetive I would say see a dr. Even if you aren't pregnant you might seriously want to talk to them about birth control options. If you prefer not using birth control pills or anything of that nature you may try tracking your cycles for a few months and trying to pinpoint when you are ovulating and avoid sex for a week before and the week after. Also you can buy spermicide inserts like Encare which you insert about 10 min before penile insertion. If you combine the insert and the withdraw method you would be better protected from any accidental sperm. It cost about $9 for 12 inserts, but that's much cheaper than a kid, lol. :)
