Urinating a lot missed period had blood and burning urine?

UTI and pregnancy?: Blood in urine with frequency/burning is suggestive of a uti/urethritis. Missing period is likely if you are sexually active, especially if u have been regular. So, i would recommend getting a hpt to see if you pregnant. U may need to see doc to get urine tested for uti/urethritis etc...Otc uristat (phenazopyridine) may help with burning/urgency. Good luck.
