I've Been Having Painful Spasms In My Left Temple Since

I've been having painful spasms in my left temple since I was around 12. I'm now 32. It use to bother me about twice a year. As of a year ago it comes and goes every month. I'm pregnant with my fourth child and I get them everyday. I have Multiple Sclerosis. I'm not able to take my meds for my illness or depression. Could I be stressing causing more spasms?
