Happy Saturday to everyone!

So I've been taking Seasonique for maybe three years now. I have an alarm that goes off so I can take it at the same time every evening. I have no idea why but I've been spotting (alternating from spotting to goddammit I need a tampon) FOR A MONTH. What the fuck? Should I call my doctor? I take it consistently and I have no idea what's going on. All I know is that I'm sick of only wearing my black underwear.
