Is Primosa for PMDD is good? Condition?

I have been on antidepressants since last 6 months due to extreme suicidial thoughts and I attempted few times. My psychiatrist tried to taper off the medicine observing my improved condition and it went well for month or so. But then suddenly I started exaggerated PMSing in which I tried to do suicide from last 3 months. My psychiatrist advice me to go for gynecologist to check for PMDD. I consulted one doctor today and she said it's quite normal and she gave me Primosa tablet 500mg BD. This month my periods are delayed by 4 days and I have been feeling extreme bodyache and body shivering. My current antidepressants is desvenlafaxine 100mg and agroprex. Is prescribed medicine is good or not for my current condition?
