When does the egg burst from the ovary..before, during or after the extra cervical mucus? - cervical mucus just when period is due

My husband and I had sex on Sat, and Sunday, Monday and Tuesday I have a lot of mucus, which means that ovulation. I wonder when the egg leaves the ovary. It may also come to slime body, but not without an egg? I just want to know about the chances of pregnancy.
