Not ovulating?

Cindy
If you skip a period, does it mean though didn't ovulate? I was did Feb 28 and still nothing..on the 27 I had very very very very light pink spotting when I wiped...I mean so pale it was barely noticeable. I've taken tons of pregnancy tests and they have all been negative. I'm guessing it's probably just the amount of stress im under. Also, will that affect me ovulating this month?? According to my calendars, I was supposed to ovulate march 16...and I had sex on the 15...just wondering what the chances are of getting pregnant...any advice would be welcomed
