Late Ovulation?

Madeleine • 2 Angel Babies and 1 due Feb 2019

I'm only on my 2nd month off of birth control, and I don't know if my cycles are regular or what. Today my BBT jumped and my CM is that egg white consistency, but I'm cramping and, if same cycle length as last month (30 days), should start my period in 2 or 3 days. I'm wondering if it's possible I'm ovulating on day 27 of my cycle...?
