I think you’re asking the wrong question. Though to answer the question you asked, yes, of course. I can’t help but think, though, that your question is akin to “I’m 45, is there a man out there who would marry me?” But you wouldn’t want to marry just any man who would be willing to marry you and you wouldn’t want to join just any convent that would accept you.
Better questions are where is God calling you? What spirituality are you drawn to? Are you looking for a cloistered life or an active life?
Do you see yourself as a cloistered nun? A teacher? A parish pastoral associate? Are you drawn to the Franciscans? Benedictines? Carmelites?
If your passion and your calling is to be a cloistered Benedictine, then you should be checking out Benedictine monasteries. If your passion is to work a “day job” while living in a community of prayer then you should be checking out active orders that live that way.
Many communities will state age limits, but not all. And even when an age limit is stated, it may be flexible. I have a dear friend who came into the Church through RCIA. During the time she was in RCIA she discovered the Poor Clares and fell in love with them. She attended Mass with them regularly and talked with the nuns when she could. Once she was received into the Church she wanted to join them, but they told her she had to wait two years before she could apply. That was worrisome since she was already more than 20 years over their age limit, but she waited. Ultimately she did enter the monastery. She was hardly their ideal image of a 20-something postulant, but it was clear on all sides that this was where God was calling her and this was where she belonged. The point is, she didn’t go around asking “I’m over 50, who would take me?” She joyfully pursued the dream that she and God shared for her life.
Are you seeing a spiritual director? Are you exploring different orders? Where are you being called?
