What are my chances with 3 follicles?

Today is CD 14 and I just had my second monitoring ultrasound. I took 5mg of letrozole this cycle and will be doing timed intercourse. It was confirmed that I have 3 mature follicles, 1 that is just shy of 20mm, 1 that is 16.5mm, and 1 that is 16mm. My RE said the two that are around 16mm are considered “medium sized” follicles, but they look healthy and I will likely ovulate 3 eggs. I’ve been trying to do some research about my chances of conception with 3 eggs vs 1. Does anyone know the stats of pregnancy with ovulation multiple eggs vs just 1? I’m diagnosed unexplained infertility and have been TTC for 2 years. This is the first cycle that I’ve had more than 1 follicle so I’m trying not to get my hopes up. Anyone have success with 3 follicles vs cycles with only 1?? Thanks!
