HELP... I'm Sooo Confused..

Janette
So I went to confirm if I was pregnant today (at a free pregnancy testing place).. While in back she told me that but was negative and said it an UTI.. While telling me she's like ohh now its turning positive but faint.. I'm freaking out like what's going on.. She says just make an appointment with a Dr.. As soon as I got out I found a Dr I could afford n they will see me tomorrow morning.. I'm Sooo SCARED N WORRIED now so I bought another test and it came back positive immediately.. I did notice white flakes in my urine (because I put a sample in a cup) Is this normal.. I should of started today but of course I took 2 test earlier.. One on Saturday n one yesterday n well now one today.. 😞
