Help I’m worried!! Gush of blood and clot

I’m 13 weeks and 6 days, about 3 Weeks ago when I went into my doctors appointment the told me I had a hematoma and that would come out gradually. Today I Went on a mile and a half walk and it’s the most exercise I’ve done in at least 5 months I work a office sit down job so I don’t move that much ever, about an hour after I started gushing blood and a big blood cot came out I called my doctor and he said going to the ER would be a waste they won’t do anything, unfortunately there’s nothing that we can do about bleeding but if you’re worried about needing a blood transfusion go, The only other reason to go would be because you keep filling up pads every hour. that’s all he said. What do I do ??
