Period question? Every one of my periods are exactly the same. First day is med, second day is heavy with clots, 3rd is med/light, 4th day is light/spotting, 5th is my last with very light spotting. My question is....is it normal to have clotty periods on your heavy day? Every time I stand up or cough or sneeze or something I can literally feel a clot come out. I really hate it. And when I was in the shower one came out. They are all smaller or the size of a quarter? Just making sure it's normal I don't have a doctor right now and I haven't thought of asking until just now.
