Protein in urine

I had my 37 week checkup today. My blood pressure was good, my cervical check was good (it’s softening but not dilating), the only thing was that I had +2 protein in my urine & I was sent home with a jug to collect my urine for 24 hours. I asked my doctor if there’s anything to worry about & she seemed to think everything was fine & said that it could be normal, but everything I’ve read on google says that they had to be monitored at a hospital or put on bed rest (So basically nothing good came of it). I have had some swelling in my feet, nothing excessive. I was told that it was due being dehydrated so I’ve upped my water intake & stayed off of them & they went back down. Other then that I haven’t had any other symptoms of preeclampsia, which I know is what they are checking for. Has anyone had this happen to them & nothing actually came of it?
