Hi there. Well, you absolutely risked pregnancy. Pulling out does not work to prevent pregnancy. EVERY male emits sperm during intercourse before they have an orgasm through pre ejaculate. Little bits leak out that have sperm within and that is just enough to get a woman pregnant. USE a condom each and every time if you don't want to get pregnant.
Take the test tomorrow. Hopefully it is negative. If it is, your period is just late which is also normal. Lots of things can cause a period to be late. Stress, illness, weight gain or loss, changes in routine, etc. can all affect a woman's cycle.
but you need to take a test. good luck
How late was your period when you had the scare? How late can a period be?
Just stay cAlm it could be stress I've had that happen to me before and I wasn't pregnant
