Lately My Periods Have Been Crazy. They Recently Last Longer

Lately my periods have been crazy. They recently last longer than 7 days. About 3 weeks ago I had protected sex. Took the morning after pill Bc he was scared the condom broke. Lately I've been hungry, constipated or just straight diarrhea, and super tired. I come home and sleep from 5 to about 7 or 8. Up for an hour. Then sleep the rest of the night til about 7 in the morning. These periods are also heavier and the blood is different than normal periods.
