Follicle Scan

I have two follicles that are 19mm and 16.5mm. Has anyone had a successful iui with these numbers? The 16.5 mm is on my left side which has a blocked tube. The right side is the one with 19 mm. My doctor said there’s a chance the right tube could pick up the egg on the left side. Do I still have a chance with a 19mm follicle on the right? I am triggering tonight and going in for an iui on Monday.
