What could be the cause of abdomen pulsation/movement/fluttering? I am a overweight female with a history of pcod but my cysts are clear in the usg done in june. My thyroid level is normal but have a pulse rate issue with normal blood pressure. I started excercise but not able to see any change in the belly fat and weight,I remain bloated and have upset stomach since 2 months.My belly looks like a  pot shaped swollen belly, I am so worried it looks like a pregnant lady although i am not( and these movements/pulsation are scaring me, I did my upt, usg and beta hcg but all the reports are normal) Kindly suggest what is wrong going on with me. Are there chances of cryptic pregnancy or anything else is happening with me. Please suggest me what to do.
