Respected use, hi I evaluated your query thoroughly .
* First of all , only blood in urine is not going to be like your narration as
long darkish thing . It seems else than normal blood in urine , I think it
more of uterine product rather than only blood in urine .
* Stomach fluttering is in concern with gastric cramping , breast changes
from
hormonal changes
* Suggest to get a urine laboratory test ,
Ultrasound of abdomen & pelvis to
confirm the diagnosis & further management guidelines .
Hope this clears your query .
Welcome for any further assistance .
