Dealing with it all

So normally my period symptoms hit BEFORE i get my period. They normally consist of light cramps & back pain, and occassional bloating. This time though, every symptom hit at once and hasnt stopped for 2 week! Im bloated, my breast hurt to the point taking a shirt off is a pain, heavier bleeding, bad cramps & lower back pain, feeling nauseous... I bled right through the pad i put on last night. Any suggestions for managing these symptoms? I can only take Tylenol for pain.
