Period

I have always been irregular. I have changed the way I have been eating and trying my best to do away from carbs. I have only lost about 8lbs however, I got my period Jan 26th and then two weeks later it came again. Since then which was feb 16th till today I still have it. I’m a little worried. I don’t know if its my change of diet or something else. It’s a normal period, darker in color. Not too heavy. Has anyone gone through this before. I don’t feel any pain. I called my gyno and I am waiting to here back from him. Just a little worried.
