If you want to know when are you ovulating from the left ovary, you would get to know it by what is called follicular studies,.
In this study you need to undergo ultrasonography
of the pelvis from day 9-10 of your periods regularly as your gynecologist advice, it would help you know when are you ovulating from left side.
It is good that your cycles are regular 28 days even after ectopic, this is a good sign, as it indicates that there is no hormonal
imbalance, which is common after ectopic or abortion
Don't worry, take care.
All the best.
