This totally happens to me sometimes, but I haven’t yet found an answer for this question. I would assume that it happens because when we sneeze, our body tenses up and that causes whatever blood there already was in our vagina to come out. It’s a weird feeling isn’t it? To sneeze and feel blood rush out. I haven’t yet gotten used to it – it still gets me every time.
What a great question! I’ve often wondered that myself. My best guess would be that a sneeze is such a short, intense action by your body (and I do believe that you contract all the way down through your diaphragm) that it acts like an accordion and gets everything moving. While you’re having your period, your uterus is contracting to move the unused lining out, so a sneeze probably just helps that process move along a little harder and faster. Again, that’s just my opinion after paying attention to my period and asking questions for lots of years. Please be sure and read Sandy’s answer for the medical explanation; I know I plan to!
Oh i think its just your muscles squeezing and pushing the blood out. Once on the bus i thought ny flow was light so i only had a liner but i had the worse cough ever and i kept squeezing more and more out. It was bad!" - Just My luck
