5 weeks and spotting ?

So Tuesday I went to the bathroom and wiped and on the toilet paper is was light pink and I went to the doctor and they said there was alittle blood in my urine and could be a uti and ended up not having a uti. So today I went to the bathroom and noticed a couple drops on my underwear but couldn’t really tell the color because of the color of underwear but when I wiped there was nothing. I called the nurse and she was telling me it should be normal in early pregnancy but miscarriage can always happen. Now I’m freaking out!!! Has this happened to anyone and baby ended up fine?
