Strange question

Lacey • I am 33. Married for Eight years. I am a dental hygienist. My husband works in industrial mechanics. We have a 2 year old little girl and are trying for baby #2
I'm a week late and still testing negative. If I skip my period and I'm not pregnant, is there a chance I would ovulate twice in this cycle? I have been off the pill since June and been regular since then until now.
