Following my only time of ever having sex, would 24 days be long enough for me to be able to take a pregnancy test and for it to be accurate?

Yes: I hope that you get the result that you want. Welcome to a new phase of your adult life -- one with new responsibilities, new fears, and new joys. Whatever your experience was, I hope that you will always cherish the memory of having given and received love. Human love is never perfect, just as people are never what we'd like them to be. But there will be wonderful times.Love wisely, and love well
