Ladies Help! Does this mean I’m getting close

Second ultrasound scheduled for Wednesday CD 10 took and OPK tonight and it’s almost positive. Do you think I’ll ovulate before my second ultrasound. I’m super nervous! This is a medicated cycle 7.5 mg of letrozole. Does letrozole cause fault positive OPKs? I know Clomid does but I don’t know about letrozole.
