Hey ladies. I am 5weeks today. I got my first positive pregnancy (digital clear blue) at 10 DPO. I drink a gallon of water daily (something I did before pregnancy) so my urine is usually always fairly diluted. This is first morning /yellow urine. Considering I am 19 DPO is this dark enough? My symptoms are very mild so naturally I get concerned if my HCG is increasing or not.
