Last night I used the restroom and wiped and there was the SMALLEST dot of pinkish blood on the toilet paper, the size of a dot of a pen on a piece of paper small. Then I looked in the toilet and there looked to be a small pea sized thing of blood but it was pink? I was so confused but thought nothing of it. Later on I went again and nothing on toilet paper but same small pea sized thing of blood was there again. This morning I wake up and use the restroom and this came out on my toilet paper but nothing in toilet. My supposed period started the 22nd. What could this be?
