Another period already??????? What should I do?

My period came on March 22 and stayed on for my usual 7 days. During the entire time it was light. Not spotting just light. My cycle it usually super heavy. It went off March 28. Its April 1st and its back on already. I haven't had much of a desire to eat but regardless I feel like I'm going to vomit. Do I go to the doctor or should I just ignore it?
