No, the wound inside the pierced areas are still open even after 2 weeks. This is a wound inside the body and it takes longer than a month to heal properly. The ears are sensible areas to be pierced on. It can take 4 months to heal just as it can take 12 months or more. So, during the healing time, you don't change your earrings. Changing them can damage the wound inside and cause irritation which can lead to infection and your body can try rejecting the foreing bodies (the earrings). So, next time you have other piercings, don't change them after 2 weeks, and if you ever need more answers, you can always reach out to a professional piercer as well. :)
