I think one major sign that God is calling you to a particular vocation is a deep peace of mind and soul.
For example, I once discerned a call to religious life. I had emailed an Ursuline sister and, more extensively, had talks with a local Carmelite nun and had a priest as a spiritual director. The Carmelite was in touch with two communities, one of which invited me to a 'come and see' with them. I also viewed a DVD (I believe it was loaned to me by the Carmelite) about contemplative spirituality. I found it all very interesting, but something didn't quite settle into place. There was some degree of unease about it for me personally, as much as I continued to look at it and perhaps tried to make it fit, if that makes sense.
Fast forward to 2015. I met a man who I fell completely, head-over-heels and walking-on-clouds in love with. When we began to first discuss marriage and having a family together, that's when everything fell into place. I knew then, just like I know now, that I want to spend the rest of my life and eternity with him.
I think you should continue to pray often to discern your vocation. Spend a lot of time with the Lord in silence. Perhaps keeping a journal of your experiences in prayer, adoration, etc would help you. Then you would have written evidence which would outline when He would draw your heart to Him and toward which vocation.
