Stopped Birthcontrol!

Ok so about a week ago I stopped taking my birthcontrol because it unfortunately was giving me high blood pressure. I was "supposed" to start my period this past Monday, but it hasn't come. When I stopped taking the pill, I bleed for about two days. I've read some things online that say you might not have your period the month you quit birthcontrol because your body isn't used to creating its own hormones. I'm just wondering if I should wait it out a little while longer (since I'm only about 4 days late) or should I talk to my OBGYN? 
Ps- I am sexually active, but we always use a condom EVERY TIME. And it's never messed up/fallen off/ torn so I know I couldn't be pregnant.
