thanks for ur query
see some history is needed to take here?
any history of delivery in the past???
if yes then normal vaginal or caeserean section???
if normal vaginal delivery
then any difficulty during that delivary???
i think meat like fleshy particles during ur menstrual period is nothing but blood clots
for which u need not to worry much
but same particles also coming out through urine is probably suggesting some fistulous tract b/w ur urinary tract
and reproductive system , may be urethro-vaginal fistula
or something like that
for that u need to undergone investigation and proper examination
do consult a gynaecologist immediately
