blood in the diaper..

Shiara • Im an 18 year old FTM, engaged to the love of my life, the beautiful man who gave me my perfect little son 😍 15/18/16💙
My son was born the night of the 15th, and lastnight he had a great big pee (yay) but when i changed him, there was a spot of blood down there (in the front of his diaper) I freaked out and checked him over, he is quite chapped on his testes and behind his bum hole, so im thinking the blood probably came from his balls? It was abit smaller than a penny and was in front.. Thoughts? Has this happened to anyone? Normal? Anything to help!?
UPDATE:: midwife said its totally normal and could continue for a few days. Its bc his pee is so concerntrated. :)
