Talk to Gynecologist on Ovulation

I have a question from any gynecologist. I m 27 years old trying to conceive. I have 27/28 days of cycle. And my periods lasts for 3 days always. I have read everywhere that ovulation occurs 14 days before your next cycle - 14th or 15th day. But I wanted to know that is it possible to ovulate early right after your periods? As I feel symptoms of ovulation right after my periods like from 7th - 9th days. I feel I ovulate early and never on 14th or 15th day ... Please tell if its possible or its just my misconception?
