TMI PIC!! Is this normal??

Haven't had my period in 3 months, started BC a month ago, took a preg test beforehand tests came out neg. have been spotting Monday and Tuesday, yesterday(Wednesday) I had incredibly painful cramping. Was nauseous and had terrible heat waves, could barely walk. Today I woke up with a very very bad migraine and have a ha ever flow than I've ever had. My hubby walked in and freaked, I'm assuming it's normal just tissue from my period, but he's insisting on my doctor or at least ask "people on glow" for advice. His words.. Lol.
