Someone please give advice TMI 6 weeks

So last week I started spotting brown and some pink. Not a lot at all. I went and got my levels checked and everything was fine it stopped the next day. Well a week later last night I had some bright pink spotting. I woke up this morning and it was light brown and some pink. I went to the ER and they gave me an ultra sound and my HCG was at 25,563. Last week my HCG was in the 6,000s. Now I’m noticing some pink discharge in my underwear and it’s more of chunky kind of. Has anyone experienced this?
