Usually, the magazine will make a preliminary screening and review after receiving the contribution. If it thinks that the work is likely to be published, it will enter the editorial department for further review. This process takes some time, so don't worry. Generally speaking, waiting for a week without an answer does not mean it is over.
I suggest you wait patiently for a while, and you can take the initiative to contact the magazine to ask about the submission. If the other party says that your work is under review or needs more time to evaluate, then you can continue to wait patiently. If you haven't received a reply or been rejected for a long time, please don't be discouraged, try to reflect on your work and writing skills, and try to contribute to other media to show your talent and creativity.
