what do I need to do?

Okay y'all serious question!!! I smoke cigarettes I'm not on any medicine not even BC! I'm starting to get sick when I smoke! Is that a sign of pregnancy? I'm cramping really bad! My boobs are really tender but I had some bleeding my normal period is 3-4 days it's been 7 and I'm still bleeding. My hips really hurts! I just need some references on what it could be.
