Period late?

So I have been on BC for two months and I decided to take the placebo pills early so that I wouldn't have my period on my vacation (at 3 months). I took the first pill last night but I have hardly seen any blood. I had some clear discharge about 3 days ago and I've had period symptoms lately such as bloating and cramps. I'm just starting to get real paranoid and I'm not sure what to do. It doesn't seem possible for me to be pregnant because I have not had sex with my boyfriend. Anyone have any suggestions? I'm just getting really worried and paranoid with all the symptoms that I am googling.
