HI
Well come to HCM
I really appreciate your concern, it seems to be multiple symptoms you have, abdomen pain could be due to
smooth muscle spasm it can be
colic, may renal, biliary depends upon the location of pain, increase frequency of urine may be sign of
urinary tract infection but in absence of associated symptoms it is less likely, what the blood you saw could be menses blood.
Most of the nonspecific abdomen pain comes around on its own and no medicine needs for that, if the pain persist then underlying cause would be matter of concern and for that it needs some tests.
If we suspecting urinary tract infection although it is very less likely still urine test is must.
If you go for urine test it will clear the doubt of
hematuria.
Diet is nothing to take anything with all of your complaints, I would advise you to wait and watch but it will be fine soon, if the symptoms persist then it requires clinical examination and testing, hope this information helps, take cares.
