I read recently that a normal period is 10-35 ml of blood. A normal tampon holds about 5 ml. On day one of my period, I easily soak through two normal tampons, so I know I’ve bled at least 10 ml by the first day. My period is significantly lighter after day 1 (and only lasts 4 days), but I still feel like I maybe bleed more than 35 ml of blood. Is this normal? It doesn’t FEEL heavy to me, but now I’m questioning whether it’s normal. I don’t have bad cramps or anything, either.
