Helpful tips for severe period pain.

Erica
For years I've had very painful cramps during my period but that last few months I've actually been in so much pain, I'm losing my train of thought and sometimes, even falling to the ground in pain. 
I'm due to start my period in two days and I'm looking for pain management techniques I can do at home to get through it before I can see my doctor again. I feel like I take a lot of over the counter pain meds for the pain but I'm looking for something more natural. Please help. Thanks in advance.
