Ovulating on my own?

Ke

We just finished 6 rounds of Letrozole. We did three rounds of 2.5 mg and ovulated once and did three rounds of 5 mg and ovulated once... Dr referred us on to an RE, my appointment is Monday... We decided to take this cycle as a break from tracking and monitoring everything. But today is CD17 and I caved and decided to take an OPK to see if ovulation had passed and this is what I got... Am I ovulating naturally on my own this cycle?? Should I keep my appointment for Monday or see if this cycle works naturally? Anyone else had this happen??
