Just got into mass effect and wondering if I should play the dlcs

I recently bought mass effect legendary edition and I finished me1 and am a couple hours into me2 and I just found out that the first second and third games have dlc, is it worth going back and playing the dlcs for me1 then continuing me2? or should i skip them, play me2 then the me2 dlcs and do the same with me3? im loving the series so far and I would like to know what you guys would recommend, thanks!
