I heard using the pull-out method can still get you pregnant, because of the precum. How about if you pulled out like 5 minutes before cumming? If so, what are the signs of pregnancy and when can you take the pregnancy test?
ANY sexual contact can result in pregnancy.
Precum can happen at any time so an arbitrary time limit won't necessarily work.
Use protection, before any sexual contact occurs.
Often, the first sign of pregnancy is a missed period. Sometimes you can have light spotting, no pad needed, a week or so before your period is due. You can test as early as two weeks after having sex, three is better, but use your FIRST morning urine when you test, your wakeup urine, for best results.
Hope it helps.
