Hi. welcome. I hate to tell you this but many, MANY women get pregnant from the 'pull out' misconception. It doesn't prevent pregnancy, AT ALL. All men emit pre ejaculate before they have an orgasm and this pre ejaculate has sperm in it and wa la, woman gets pregnant.
with that said, women also can be late for a variety of reasons.
You need to take a test. Go to any drug store, grocery store, super store, convenience store and buy a test. And a huge box of condoms. If you have sex, you MUST use protection. Test first and let us know what it says hon. good luck
You could be pregnant the only way to tell would be to take a test the pull out method is not a safe way to have sex and accidents happen. The sooner you find out for yourself the sooner you can make a decision with your boyfriend on what you are going to do
