I had a miscarriage three months ago. I had my period like normal since them, but my ovulation was messed up. This month was ALMOST back to normal, but my period is crazy heavy. I bled through two tampons during the night, and another this morning in an hour. I also have a migraine, none of which is my normal. I usually have light periods, and no headache... I've read that it can take a couple months for your cycle to go back to normal, and that if it takes longer, a heavy period can actually be a good sign that your body is finally getting balanced again. But I still worry... I've never felt this miserable during my period before.
