is the worst part over?

I started spotting Thursday at 7 weeks. Hcg was 4200. Spotting continued Friday, then this morning bright red heavy bleeding started. Hcg tested at 3500. I had about an hour of really painful cramping. I've taken Tylenol and the pain has subsided, still bleeding heavily. For those of you who have gone through this before, do you you think the hardest part (physically) is over? Just wondering what to expect.
