What Causes Throat Irritation And Green Colored Stool During Menstruation?

Hi, I am 17 yr. old female. I weigh 175 lbs and I am 5'3". I have been on my period for about a week now and there are little clots in my blood. Also, my throat is very irritated and my stool has been a greenish color for a few days. I have also been very sleepy for the past couple of days and don't seem to be waking up on my normal schedule. Is there any relation to any of these problems or what?
