Timing for Ovulation. D10 to d20 phase?

Hello, I was taking ovary stimulating injections during my last menstrual cycle during march. I developed 3 eggs. Lockdown imposed by then and I did not receive any HCG or trigger shots for my ovulation. Then I got period on 8th April, 2020. Now I want to know, 1. Since there were 3 eggs developing last cycle, when my treatment stopped, what is the chance that all 3 eggs ruptured during last menstruation on 8th April, without HCG injection is it possible?? 2. What is the chance that only one egg ruptured without trigger shot and two eggs remaining. 3. What can be my chance of ovulation during this cycle, how to calculate it. Whether the 2 eggs remaining from last cycle can ovulate earlier than normal D10 to D20 phase? How to track ovulation and plan intercourse for this cycle
