Menstruation

It's been nearly a month since it happened but I'm still curious. I started spotting and thought it was nothing since it went away and then days later my spotting came back for nearly 11 straight until I had my period and since I was bleeding so much and hadn't had my period for a while (doctors request) I decided to just stop my pill and bleed it out until my period naturally stopped which took about 8 days on top of the 11 days I was spotting so I was bleeding nearly 3 weeks straight. I got internal and external ultrasounds and blood tests done and there was nothing writing but I've never had spotting issues so bad. My periods also usually only last 5-7 days normally. Cramping was really bad too even when spotting. Just wondering if anyone else has had similar issues?
