Pill side effects

I just started taking the pill a week ago. I have had sex since then (with a condom and he pulled out.) I have had that feeling you get before your period (cramp-like but not painful) for the past few days, I feel as if I am bloated, and my acne is a little worse than it normally is... I am curious if these are normal side effects of the pill? My period normally wouldn't be due for about 6 more days and it is normal for me to get these symptoms about this time but not as strong as they are right now. I am very paranoid, but I don't want to worry anymore than I have to. Thanks! :)
