Thanks for the query.
If your partner hasn't ejaculated inside your vagina during the intercourse then the chances of pregnancy are minimal and you should not stand worried as 3 strokes usually don't build up the precum either. So rest assured, it is unlikely that you are pregnant.
Hope this helps.
