When do your HCG levels drop?

Lindsey

How long does it take for your HCG levels to drop after D&C?? I had a D&C on October 28th and i just took a pregnancy test after having 2 high ovulation tests and my husband and i saw a vvvfl on the pregnancy test??? I didn’t know if my levels are still up or what. I have yet to have a period since my D&C! Please help!
