Should I bother?

My doctor wants to give me Yasmin due to bad pms every month. I am already on meds for mood disorder but they don't seem to budge the monthly agrivation and aggitation I suffer. I am 43 and do not need a BC pill as I had my tubes done a few years back but he feels this may be the answer for the pms. I had an oblation procedure done last year and only have a 3-4 day mild period anyway. Is anyone else in this situation? Should I take this pill ?
