What Causes Severe Abdominal Cramps, Nausea And Dizziness During Menstruation?

I am a 37yo female who has unbearable menstrual cramps, cold sweats, nausea, and feelings of faint when I start my period for the first couple of days. The first couple of days the pain is like contractions. Bleeding isn t so bad during this time, its not usually heavy till day 3. I have tried pain killers, anti-inflammatory, hot baths, heating pads, (you name it, I have tried it).. I have always had painful periods, but since my tubal in 2006, that s when it started becoming unbearable.. I had a trans vaginal ultrasound done on 07/08/2014, but have since lost my insurance, so I have the results but don t know what they mean. Uterus is anteverted and slightly retroflexed measuring 8.7x4.2x4.5cm. Have endometrial stripe 8mm thick. Small nabothian cyst ii s seen in cervix. Right ovary 2.3x1.6x1.9cm and demonstrates cyst 1.6x0.8x1.1cm. Left ovary 2.7x2.0x2.1cm and demonstrates follicle or cyst 1.0cm.. What does all this mean?
