I've never really kept up with ovulation dates. But for the most part my period has come when its expected and when it doesn't it was because I was pregnant. Last period was on Sep 19, 2011. Af hasn't shown. October is a long month but what do you know, no AF. Around the time I expected it to show I did get discharge (gooey mess - whitish/clear color)sorry for TMI. A few days later I started cramping and thought I was going to start but the cramping stopped. I've just never missed a period in any one month. So, how late can one ovulate? Week before AF, days, before, day of? Sorry..you would think after 3 kids I'd know this but I don't. I'm just wondering if late ovulation is what delayed AF but to delay it this long seems odd to me.
