uh oh?

So... I started spotting the day of my last pill (Friday) which isn't uncommon for me. However, now it has completely stopped. This has never happened before. Now I haven't taken a pill for two days and nothing. I've never stopped once I've started and it's freaking me out. I've been waking up in the middle of the light with hot flashes. No morning sickness or anything but my mom didn't get morning sickness so Theresa good chance I wouldn't either. How long should I wait to take a test?
