I suggest you send the editor an email just to inquire what is happening! However, depending on how busy the journal's editor is regarding the number of submissions, it is possible! I have written a paper, viz. “Writing for Publication for Students and University Staff”, which also discusses the review length of time and suggestions of what authors could do. The paper is freely available on ResearchGate: https://www.researchgate.net/publication/342549330_Writing_for_Publication_for_Students_and_University_Staff.
