blood in urine ???

I had light spotting a few days before my doctor visit , I've been feeling the need to pee all of the time , some food doesn't sit right with me sometimes , weird cravings , my breasts have been bothering me sometimes my nipple hurts and they really itch . Went to the dr They did a urine pregnancy test/ uti test And I am so confused. Because they said that I do not have a bladder infection no urinary tract infection, my pregnancy test was negative but she said there was blood in my urine which they only see in pregnant people and women on their period And I'm definitely not on my period. So she told me to come back in a week or two .... what to you ladies think?
