Unsure?

Caitlin
Hi guys, I have a few questions and was hoping to get some help!!
I stopped taking my brown pills (off week) of birth control a week ago bcs I had missed a couple and thought I was pregnant. Took a test said negative, but have been off the pill for a week, and have had unprotected sex about 4 times or so. Does any one no what the chances are if I have ovulated yet or not? Since stoping my pills I have not gotten a period, that's all I know! 
Please help!! Thanks!!
