Confused

My last period was August 2nd. It lasted 6 days. My cycles are usually 28-30 days. In the chart it says I was suppose to be ovulating this week but I feel I am not ovulating this week because I feel so dry down there sorry tmi. I feel like I ovulated right after my period. I want to say maybe like 2-3 days after my period because I had a lot of egg whites discharge for that week after my period. Is this happening to anybody else. Have you gone pregnant like that? I know I read a lot ovulation but is so confusing God. Please ladies I need answers.
