Ovulating..

I was on birth control for years and I stopped taking it about a month ago, because I was having a reaction. I had the egg white consistency discharge, that had no scent to it. I was told that it is probably me ovulating, but my periods are so irregular that I have a hard time knowing my cycle. I am tracking it on a period tracker. 1 cycle was 33 days the other was 48. I'm so confused on what's going on! This has never happened because I've been on birth control so long. Any advice??
