My period started 20 days ago and as usual it started heavy then got lighter. But for the past 5 days I thought it would be coming to an end with a little spotting but it’s been getting heavier ?? I had a miscarriage last year and this is completely different, I don’t have cramps or any large clots coming out. Any idea what’s going on? I’m not on birth control and my periods usually last 9 days max.
