Every night around 2:30am for 4am I wake up and feel sick to my stomach.. I won't vomit, I don't feel the need to the whole time but always have that pain and the feeling to vomit comes and goes.. I currently have the bar in my arm for birth control and take the pill also to have control of my periods.. Since I've been feeling sick every night I've stopped taking the pill to see if that was it but no and I am not pregnant.. Why am I always feeling sick! I've had it for a long time
