Ok so I stopped AF two days ago! But my lower back is still killing me the way it was when I started! All night at work I had the worst cramps low down on my stomach. I'm worried. Could it be my kidneys or what! I feel like I've just felt yukie for the past while and I don't understand why! I'm falling apart it seems. I dunno what could be the cause. And tonight I'm extremely bloated and gassy! I just wanna feel normal again! 😩
