mefanamic acid & periods

daydreamer

today I picked up this prescription from my pharmacy. I was wondering if anyone had any positive effects after taking them? I'm taking them because if I get back pain (which is so intense I have to sit or lay down and then it still kills) its usually on my period and its really hard to live normally. I also have heavy periods as it is (although my doctor thought otherwise when I couldn't tell her how many pads I used each time I have my period. I mix and match the type of pad so its hard to keep count). I'm not sexually active or on any pill or birth control. I just dont want to be treating this pain when I am not 100% sure I have simply period pain. my doctor thinks I just have period pain like everyone else but everyone else can get on with their lives and I really can't for that week I'm on my period. also I dont get any sort of stomach cramps. I had an ultrasound and they couldn't see clearly. the lady who did the ultrasound recommended an MRI and all I have are these poxy tablets! I feel like something is not right and that my doctor doesnt understand me! anyone had anything similar? sorry for the rant!
