It can be pretty gross, but is completely normal

It can be pretty gross, but those spots are just the ejected blood from the lining of your womb. The blood could look anywhere from bright red to dark brown, which is perfectly normal. The amount of menstrual blood you have is different for each woman but most have heavier bleeding at the start, and then it lightens up until it’s all done. Sanitary products like tampons, pads and liners come in a range of absorbencies. This is so you can use the ‘super’ absorbency products for heavy days, ‘regular’ for medium flow and ‘mini’ for light days
