Could i be ovulating right now?

So, to try to make a long story short. My last period was june 2nd. I don't take my basal temp so I just monitor my body! I don't even know my luteal phase! All the calendars that I check says that I will ovulate on june 26th but I have lots of white discharge! Sorry if TMI but dh & I bd tonight and 2 days ago! The same thing happened to me last month & the calendar said I would ovulate on a certain day but I started seeing white discharge a week before but when the time came for me to ovulate based on the calendars, nothing was there! So, someone plz help me! Am I ovulating today? Why does it seem like I always get this white discharge a week before the calendar time? Why? Please help
