I’m scared

So I been feeling funny and I went to the hospital ( labor and delivery). ( I am 29 weeks). I went and they was like my platelits might be low. They took blood and ran my urine everything came back fine except for my urine. I have a lot of protein in my urine. I was told I don’t have signs of preeclampsia I have not swelled and my blood pressure was high when I checked 120 over something. But it went down on its own in less than 10 minutes. I am now doing a 24 hour urine collection. I was told someone people have a lot of protein in there urine and they don’t know why.I am not sure what is going on. Have this happened to anyone and how did it turn out.

Edit: when I said I feel funny I have been feeling a bit light headed and dizzy. I’m not dehydrated I drink a lot of fluids.
