Am I or do I wanna be?

Ruby

Ive been on birth control for about 3 years and the past couples months ive been forgetting to take it then taking it when I remember usually the nest day... I’ve been having very vivid crazy dreams, feeling nauseous, bad headaches, dizzy, and completely exhausted. My last period ended December4th.. I took test last Friday and they showed negative. Is it in my head or am I possibly pregnant?
