I have recently started the mini pill cerelle. I had my period normally before starting the pill and i am not sexually active. In my tummy I am feeling like a fluttering pain which my friend described she was having before when she was pregnant so I'm starting to worry, there couldn't be any way that I'm pregnant because I'm not sexually active, although I also look like I have put weight on around my tummy but I was wondering is this just a side effect of the mini pill?
