Is an early probation review meeting a cause for concern?

I started my new job as a marketing coordinator at the beginning of January, right after graduating. The company has a 90-day probationary period, which means my review should be around April 3rd.

I began alongside another new hire who shares the same role but has significantly more experience from her previous job at a similar firm. This is my first full-time position, and I’ve noticed that my manager hasn’t scheduled a 90-day review for her, but has set mine up two weeks in advance.

My meeting will be just with my manager and does not involve HR. I believe I have a solid rapport with her— we communicate often and share a lot of light-hearted moments. However, I know I need some extra guidance compared to my coworker, as this is my first time taking on such responsibilities. I’ve been thrown into the deep end with this role, leading me to learn a great deal independently, but I always seek assistance when needed.

Given all of this, could my early review be a sign that they might be considering letting me go, or am I overanalyzing the situation? Also, why hasn’t my coworker received a review meeting? I’m feeling quite anxious and would really value your thoughts!
