Help!!!

I used to have a nexolanon implant in my arm that stopped all periods. When I had the nexolanon I was taking st johns wort (cancels out nexolanon) I have been taking tests and all negative , me and hubby are trying for a baby but my period has not returned since removal of nexolanon and I don’t know when I’m ovulating or when to properly test or try 🥺 someone have any advice ?
