Birth control side effects?

So I just started the pill (Junel fe is the brand) again for the first time in about a year and a half and I'm having some funny symptoms that I can't remember having before (it was so long ago though when I first ever started so maybe I'm just misremembering). These symptoms are basically like what I get before I start/during my period. Nauseous, lower back pain, feeling bloated, this awful feeling I get around my ovaries that only ever happens before/during my period and even pink discharge. I didn't start these symptoms until about 2 days ago and I only have one more real pill with this pack (besides the sugar pills). Are these normal birth control side effects or could it be from something else?
