Can't handle pms symptoms

Since goin off birth control (I was on the Nuva ring for about 7 years) slowly every month my AF symptoms have been getting more unbearable. When I was younger they were awful and Going on BC was what helped. Now that I'm TTC and that's not an option it's been hell. I get a migraine the day before AF nicely shows up bringing along extreme cramps and lower back pain... I'm wondering if anyone has tried aromatherapy , essential oils or anything like that that won't hinder conception but will give me some relief until I'm lucky enough to create my miracle.
